Exercises 1. Suppose a force acts on a 4.00 kg object in the x-direction. The force varies with time and is given by F(t)12.0t3 - 8.00 N. At t -0, the object has a velocity of 3.00 m/s in the positive x-direction. Use the impulse-momentum theorem to find the object's velocity after 2.00 s. 2. In a lab experiment, a spring gun projects a metal sphere. The sphere leaves the spring gun with a velocity of 3.00 m/s in the...

The force Fx acting on a 0.500-kg particle is shown as a function of x in (see below). (a) From the graph, calculate the work done by the force when the particle moves from x = 0.00 to the following values of x: -4.00, -3.00,-2.00, -1.00, +1.00, +2.00, +3.00, and +4.00 m. (b) If it starts with a velocity of 2.00 m/s in the +x direction, how far will the particle go in that direction before stopping?
