The train with a mass

M

has velocity that can be described by the function

vec(v)(t)=At^(2)hat(x)

.\ a. What is the change in momentum of the train between times

t=0

and

t=t_(f)

?\ b. What is the force

vec(F)

that is applied to the train at time

t_(f)

?\ c. What is the impulse experienced by the train between times

t=0

and

t=t_(f)

?
