Three identical balls are tied by light strings to the same vertical light rod and rotate around it with the same angular velocity, as shown below. a) What is the ratio of the rotational kinetic energy of the first ball to the rotational kinetic energy of the second ball, to the rotational kinetic energy of the third ball? Demonstrate the answer in a form of KE1 : KE2 :KE3 b) Imagine, during the rotation, the second string broke and second ball got removed from the system. If the masses of the balls are 100g each and initial angular velocity (before string broke) was 10 rpm, what is the new angular velocity, when only first and third balls remain rotating? c) Where is the center of mass of this system is located? 1 m ball 1 2 m ball 2 3 m ball 3
Newton's Third Law states that: A particle remains at rest or continues to move with a uniform velocity if there is no unbalanced force acting on it. The acceleration of a particle is proportional to the vector sum of forces acting on it, and is in the direction of this vector sum. The forces of action and reaction between interacting bodies are equal in magnitude, opposite in direction, and collinear. The velocity of a particle is proportional to the vector sum of forces acting on it, and is in the direction of this vector sum.
Newton's second law of motion leads to: the rate of change of linear momentum is equal to the applied moment the rate of change of linear momentum is equal to the applied force the rate of change of angular momentum is equal to the applied force the mass times acceleration of a particle is equal to the applied force
Q4) In Fig.2, The location of the tool, 77 is not accurately known. Using force control, the robot feels around with the tool tip until it inserts it into the socket (or Goal) at loca- tiongr. Once in this "calibration" configuration (in which (G) and (T) are coincident), the position of the robot, is figured out by reading the joint angle sensors and com- puting the kinematics. Assuming T and T are known, give the transform equation to compute the un- known tool frame,T. 2 Fig.2
Zorch, an archenemy of Superman, decides to slow Earth’s rotation to once per 29 h by exerting a force parallel to the equator, opposing the rotation. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.15 × 107 N. For the purposes calculations in this problem you should treat the Earth as a sphere of uniform density even though it isn't. a. How long, in seconds, must Zorch push with this force to accomplish his goal? (This period gives Superman time to devote to other villains.)
1. Determine if the following statements are true or false. If the statement is true, justify your reasoning. If the statement is false, correct the statement to make it true. a. For one-dimensional motion, deceleration always occurs in the negative direction. b. If a ball is tossed into the air, the acceleration at the top of its path is zero. c. The slope of a velocity vs. time graph represents the position of a particle. d. The tangential velocity of a particle can never be negative. e. In relative motion, n =-Ün/A
12. Glamcon F Pobiem 2.44. traveling An unmarked police car traveling a constant 95 km/h is passed by a speeder 135 km/h. Precisely 1.00 s after the speeder passes, the police officer steps on the accel- erator; if the police car's acceleration is 2.00 m/s², how much time passes before the police car overtakes the speeder (assumed moving at constant speed)?
Takeoff roll (ground roll) is the portion of the takeoff procedure during which the airplane is accelerated from a standstill to an airspeed that provides sufficient lift for it to become airborne. An aircraft start from rest and travels a distance of 1.9 km during 29 s with a constant acceleration before taking off. Analyse the motion of the aircraft and calculate, • The acceleration: m/s-2 The speed at the instant the plane takes off after 29 s: mls • The distance traveled during the first second: m • The distance traveled during the last second on ground (just before takeoff): m The speed variation Av [m/s] during the last second on ground: mls
The expression: "If the vector sum of the external forces on a system is zero, the total linear motion of the system ..." Complete the sentence with the best option that completes the expression: a) It is constant and the utility lies in that it does not depend on the detailed nature of the internal forces acting between the members of the system. b) It is constant and the utility lies in that it depends on the detailed nature of the internal forces acting between the members of the system. c) It is not constant and the utility lies in that it depends on the detailed nature of the external forces acting between the members of the system. d) It is not constant and the usefulness is that it does not depend on the detailed nature of the external forces acting between the members of the system.
1. Circle weather the following statements are true or false. If the statement is true justify your reasoning if the statement is false correct the statement to make it true or justify why it is false a. Impulse is the integral of a force vs distance graph b. In two dimensions analyzing linear and angular momentum provides up to three scalar equations. c. Linear acceleration and angular acceleration both have units of ft/s^2 or m/s^2 d. When absolute motion or a rigid body it is important to find a function that relates linear and angular position then integrate to find velocity e. Instantaneous centers can only be determined for velocity and only for a snapshot in time
