Question

At the moment when a shotputter releases a 5.00 kg shot, the shot is 3.00 m above the ground and travelling at

15.0 m/s. It reaches a maximum height of 14.5 m above the ground and then falls to the ground. If air resistance is

negligible,

*What was the kinetic energy of the shot just as it struck the ground?​

Answer 1

Answer:

562.5 J (Joule)

Explanation:

the mass of the object is 5kg

the speed of the object is 15 m/s

k.e = 1/2mv2

= 1/2×5×15×15

=1/2×5×225

=2.5×225

=562.5 j
