Question

A stone is dropped from the roof of a five-storey building The
height of each storey is 4m Talking g= 10m/s2, calculate
the velocity with which the stone will hit the ground

Height of building=5×4=20 mInitial velocity, u=0g=10 m/s2Using relation,v2-u2=2ghv2-0=2×10×20=400or Final velocity , v=20 m/sIt is the velocity with which the stone will hit the ground

A stone is dropped from the roof of a five-storey building. The height of each storey is 4m. Talking g= 10m/s2, calculate the velocity with which the stone will hit the ground.
