Question

How much momentum will an object of mass 10kg transfer to t he floor if it falls from a height of 0.8m?(G=10m/s2)

Answer 1

m = 10 kg

v² = u ²+ 2  g h
   = 0 + 2 * 10 * 0.8
   = 16

v = 4 m/s

momentum = 10 kg * 4 m/s = 40 kg-m/s
As the person comes to rest quickly after the impact, this momentum is transferred to the floor.
