Question

A 4.0 kg toy race car can move along an x axis. The figure below gives Fx of the force acting on the car, which begins at rest at time t=0.

a) In unit-vector notation, what is the momentum of the car at t= 2.0 s? __ kg x m/s

b) In unit-vector notation, what is the momentum of the car at t= 9.0 s? __kg x m/s

c) In unit-vector notation, what is th car's velocity at t= 8.0s? ___m/s

Please show work and steps thank you!! :)

Explanation / Answer

force,momentum and impulse formula can be used

momentum=mv

F=ma=mv/t

we can find v

so we can momentum
