- Question 6. The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 5.9 m/s. Neglect nonconservative forces, such as friction and air resistance, and find the height h of the highest point reached by the skateboarder on the right side of the ramp. Ans: 1.8 m AllThe skateboarder in the drawing starts down the left side of the ramp with an initial speed of 6.4 m/s. Neglect nonconservative forces, such as friction and air resistance, and find the height h of the highest point reached by the skateboarder on the right side of the ramp. iA particle, starting from point A in the drawing (the height at A is 3.00 m), is projected down the curved runway. Upon leaving the runway at point B, the particle is traveling straight upward and reaches a height of 6.93 above the floor before falling back down. Ignoring friction and air resistance, find the speed of the particle at point A. Number i Units
