Answer 1

Question:-

A force time graph for the motion of a body is shown in Fig.

Change in linear momentum between 0 and 8s is

(a) zero (b) 4 N-s

(c) 8 Ns (d) None of these

${\red{\underline{\underline{\bold{Answer:-}}}}}$

4 N-s :-

${\green{\underline{\underline{\bold{Explanation:-}}}}}$

• Area under the curve of Force-time graph gives the change in momentum of the body.

• Area under the curve Area = 1/2 ×1×8=4

• Thus change in momentum of the body between 0 to 8 is 4 Ns.

hope it helps you..
