A glider on an air track carries a flag of length l through a stationary photo gate, which measures the time interval ?td during which the flag blocks a beam of infrared light passing across the photo gate. The ratio vd l / ?td is the average velocity of the glider over this part of its motion. Suppose the glider moves with constant acceleration.
(a) Argue for or against the idea that vd is equal to the instantaneous velocity of the glider when it is halfway through the photo gate in space.
(b) Argue for or against the idea that vd is equal to the instantaneous velocity of the glider when it is halfway through the photo gate in time.
A ball of mass m falls from height h,to height hf near the surface of the Earth, as shown at right. When the ball passes it has a speed vf. Ignore air resistance, and assume that any changes in kinetic energy of the Earth are negligible.
