A 2kg toy car can move along an x axis. ...

A 2kg toy car can move along an x axis. Graph shows force `F_(x)` , acting on the car which being at rest at time `t=0` . The velocity of the particle at `t=0s` is:

A

`-im//s`

B

`-1.5im//s`

C

`6.5im//s`

D

`13im//s`

Text Solution

Verified by Experts

The correct Answer is:
C
`intdp=p_(f)-p_(i)=intFdt`
=Area under the curve.
`p_(i)=0`
Net Area `=16-2-1=13N-s`
`=V_(f)=(13)/(2)=6.5im//s`
[As momentum is position, particle is moving along positive `x` axis.]
