A15.53 kg loose bag of soil falls 5.50 m at a construction site. if all the potential energy of the fall is retained by the soil in the bag, how much will its temperature increase? (csoil = 0.200 kcal/kg oc)

ice to water 1 water to vapour 2 latent heat

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
