Question

A force of 10N acts on a body of mass 20kg for 10s .Change in its momentum is:
  1. 5kgm/s
  2. 100kgm/s
  3. 200kgm/s
  4. 1000kgm/s

A
5kgm/s
B
1000kgm/s
C
100kgm/s
D
200kgm/s
Solution
Verified by Toppr

ΔP=FΔt=10×10=100kgm/s
Where,
Δ P = Change in momentum,
F = Applied force
Δ t = time for which force has been applied on the body
