Question

91. A force of 50N acts on body for 10 seconds. What will be the
change in momentum (Bahawalpur 1992)
(a) 200 NS
(b)
500 N-S
(c) 800 N-S
(d) SN-
b c d
a
M​

Answer 1

Answer:

Force = dp/dt

,where dp/dt is the rate of change of linear momentum.

Given, F = 50N

dt = 1/10 s

Therefore, change in linear momentum,

dp = F * dt

= 50*1/10

= 5 Kg m/s
