Question

How much momentum will an object of mass 10 kg transfers to the floor, if it falls from a
height of 5m (g=a=10m/s)
a) 10kg/m2
b) 100kg/m2
c) 1000kg/m2
d) Okg/m2​

Answer 1

Answer:

Option B= 100kg/m²

Explanation:

Velocity when reached to ground

v=2gh= 2×10×5= 100

v=10m/sec

initial momentum before collision pi=mv=10×10=100kgmsec

final momentum P0

P=0

momentum transferred =Pi−P0

=100−0

100khm/sec
