Question

An athlete is practicing shotput using a 16-pound shot, and he throws it 40 feet. He then uses a 12-pound shot and throws it 50 feet. In three to four sentences, explain why there is a difference in these throws using the ideas of mass, kinetic energy, and velocity.

Answer 1

Answer:

Lowering of mass of the shot has high kinetic energy which leads to covering more distance of the shot.

There is a difference in these throws because the mass of the shot decreases which increases its velocity and as a result the shot covers more distance. First, the athlete throws the shot having 16-pound weight or mass which covers 40 feet distance.

Whereas in the second throw, he uses a shot having 12-pound it covers 50 feet distance because the mass

is lower in the second throw and the athlete can easily throw the shot which covers more distance so the second shot has more kinetic energy as well as more velocity which compels it to cover more distance so we can conclude that lowering of mass leads to covering more distance of the shot.
