A 6.0 kg toy car can move along an x axis. The figure gives F x of the force act

Question

A 6.0 kg toy car can move along an x axis. The 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 = 4.0 N. In unit-vector notation, what is  p at (a)t = 6.0 s and (b)t = 8.0 s,(c) what is  v at t = 1.0 s?

I got 40i-hat for a, 60 ihat for b and 86ihat for c and all three answers are wrong. Please provide units for part c cuz it is Thanks

Explanation / Answer

a) It looks like the force at t=6 is 4N, so the average force over the time interval was 0.66N.
Therefore p = Favg
