A body of mass 5 kg is acted on by a net force F which varies with time t as shown in the given figure. Then the net momentum in S.I. units gained by the body at the end of 10 seconds is

A

0

B

100

C

140

D

200

Text Solution

Verified by Experts

The correct Answer is:
C
Force `=("Change in momentum")/("time")`
= area of trapezium OABC `=((10 + 4) xx 20)/2 = 140` kg m/s
