A 0.67 kg ball is moving horizontally with a speed of 4.0 m/s when it strikes a vertical wall. The ball rebounds with a speed of 1.4 m/s. What is the magnitude of the change in linear momentum of the ball?

A circular-motion addict of mass 40.0 kg rides a Ferris wheel around in a vertical circle of radius 12.0 m at a constant speed of 5.0 m/s. What is the magnitude of the normal force on the addict from the seat when both go through the highest point of the circular path?

A  spring stretches 1.68 cm vertically when a 1.50 kg object is suspended from it.  Find the distance (in cm) the spring stretches if you replace the 1.50 kg object with a 4.40 kg object. Assume that the spring obeys the Hook’s law.

A horizontal vinyl record of mass 0.0522 kg and radius 0.0932 m rotates freely about a vertical axis through its center with an angular speed of 5.71 rad/s and a rotational inertia of 2.02 x 10-4 kg·m2. Putty of mass 0.0189 kg drops vertically onto the record from above and sticks to the edge of the record.What is the angular speed of the record immediately afterwards?

Suppose the coefficient of static friction between the road and the tires on a car is 0.4 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 34.0 m radius?

A circular-motion addict of mass 90.0 kg rides a Ferris wheel around in a vertical circle of radius 12.0 m at a constant speed of 5.0 m/s. What is the magnitude of the normal force on the addict from the seat when both go through the highest point of the circular path?

A puck of mass m = 1.60 kg slides in a circle of radius r = 18.0 cm on a frictionless table while attached to a hanging cylinder of mass M = 3.0 kg by a cord through a hole in the table. What speed keeps the cylinder at rest?

Suppose the coefficient of static friction between the road and the tires on a car is 0.4 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 46.0 m radius?

One end of a 2.0-m long string is fixed; the other end is attached to a 4.0-kg stone. The stone swings in a vertical circle, passing the bottom point at 4.0 m/s. The tension force of the string at this point is about:

The only force acting on a 3.5 kg body as it moves along the positive x axis has an x component Fx = -5x N, where x is in meters. The velocity of the body at x = 2.3 m is 9.6 m/s. What is the velocity of the body at x = 4.1 m?
