Hey there I see you need help well I am here to do just that, so your answer would be kinetic energy because potential energy is when her is sitting on the top of the hill so the<span> correct answer is :Kinetic Energy
Hope this helps if so why not hit that brainllest answer button ;)

Answer:
v = 12.8 m/s
Explanation:
Applying the law of conservation of energy:
where,
m₁ = mass of baseball = 149 kg
m₂ = mass of catcher = 57 kg
u₁ = initial speed of ball = 17.7 m/s
u₂ = initial speed of catcher = 0 m/s
v₁ = v₂ = v = final speed of ball and the final speed of catcher = ?
both are same because ball is in hands of cathcer in the final state.
Therefore,
<u>v = 12.8 m/s</u>
Answer:
e=mc2 made to relate mass with energy . bcoz energy can neither b created nor b destroyed
If a man has a mass of 83 kilograms on Earth, the force of gravity on his body be on the moon 135.6N. force =mass*acc , 83 * 9.8/6= 813.4/6 = 135.6N
