Homework Statement
A 7.0 kg toy car can move along an x axis; Figure gives Fx of the force acting on the car, which begins at rest at time t=0. The scale on the Fx axis is set by Fxs = 6.0 N. In unit-vector notation, what is p at (a)t = 1.0 s and (b)t = 6.0 s,(c) what is v at t = 9.0 s?

Homework Equations
p = mv
F = ma
J = Ft
V2 = v1 + at
The Attempt at a Solution
I tried solving for V2 using F = ma
f = m(v2-v1/t)
6 = 7 (v2 - 0/1)
then i plugged this value into p = mv but then i realized they want unit vector notation and I got really confused! =S
