PE=mgh
Gravitational potential energy is equal to mass(58.0g) times gravitational acceleration(9.81m/s^2) times heigh/distance from ground
I believe the correct answer is A. i hope i helped, have an amazing day:)
<span>Velocity of boy with which it hits the ground is
v = √(2gH)
= √(2 × 10 m/s^2 × 3 m)
= √(60) m/s
Boy will not rebound.
So,
change in momentum = mv - 0
= Mass of boy × √(60) m/s
So the answer would be C – best estimate.</span>
