Question
A track meet is held on a planet in a distant solar system. A shot-putter releases a shot at a point 2.0 m above ground level. A
stroboscopic plot of the position of the shot is shown in the figure, where the readings are 0.76 s apart and the shot is released at time t
= 0. (a) What is the initial velocity of the shot in unit-vector notation? (b) What is the magnitude of the free-fall acceleration on the
planet? (c) How long after it is released does the shot reach the ground? (d) If an identical throw of the shot is made on the surface of
Earth, how long after it is released does it reach the ground?
