Problem 3: A force F = 4x2 - 3x acts on an object as it moves along the x-axis. a) How much work is done by the force as the object moves from x = 2.0 m to x = 7.0 m? b) If the mass of the object is 5.0 kg and it started at rest, what is it's speed at x = 7.0 m? Please show step-by-step.
A force F = (3xi - 2xyj) N acts on an object as the object moves in the .x direction origin to .v 5.00 m (no motion in v-axis). The object has a mass m = 5.00 kg. Find the work done on the object by the force F. lf the object starts from rest, what is the final speed of the object at x = 5.00 m.?

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...
