### Classical Mechanics: Momentum and Velocity

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. (The vertical axis is marked in increments of 2 N.) See the attached document for the necessary graph. (a) What is the momentum of the car at t = 6.0 s (b) What is the moment
