5kg of ice falls away from the edge of the roof of a block of flats, at a height of 26m above the ground.
ignoring the air drag, find out:
a) how long it takes for the ice block to hit the ground.
b) what is the speed at which the ice block hits the ground.
c)how much energy it transfers to the surroundings when it comes to a stop.
The Attempt at a Solution
t=2.3s and that's the time it takes for the ice block to hit the ground.
