Asked by bob
the largest watermelon ever grown had a mass of 118 kg. suppose this watermelon were exhibited on a platform 5 m above the ground . after the exhibition, the watermelon is allowed to slide along to the ground along a smooth ramp, How high above the ground is the watermelon at the moment its kinetic energy is 4.61 J ?

If its kinetic energy is 4.61 J, its potential energy will have fallen by the same amount (neglecting friction and assuming it does not roll).
Amount of drop = 4.61/(M*g) = 3.99*10^-3 m
(about 4.0 millimeters)
Height above ground = 4.996 m
Amount of drop = 4.61/(M*g) = 3.99*10^-3 m
(about 4.0 millimeters)
Height above ground = 4.996 m
