Question
The hammer throw is a track-and-field event in which a 7.3-kg ball (the ''hammer'') is whirled around in a circle several times and released. It then moves upward on the familiar curving path of projectile motion and eventually returns to earth some distance away. The world record for this distance is 86.75 m, achieved in 1986 by Yuriy Sedykh. Ignore air resistance and the fact that the ball is released above the ground rather than at ground level. Furthermore, assume that the ball is whirled on a circle that has a radius of 1.45 m and that its velocity at the instant of release is directed 33.5
Explanation / Answer
# combination projectile motion/centripetal force problem.
First use the range equation to find the velocity of the hammer:
range= 86.75m = ((Vo)
