A golf ball (50 g) hit by a club is accelerated from rest to 50 m/s in 2.50 ms. What are the magnitudes of the impulse delivered to the ball and the average force acting on the ball? Impulse = Average Force = A disk of radius 10.0 cm spins about an axis through its center at a constant 5.0 rad/s. What is the linear velocity, centripetal and tangential accelerations of a point on its rim? linear velocity = centripetal...

A ball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. If the ball hits the floor with a speed of 3.30 m/s and rebounds with a speed of 1.50 m/s, determine the following. (a) magnitude of the change in the ball's momentum in kg · m/s (Let up be in the positive direction.) (b) change in the magnitude of the ball's momentum in kg · m/s (Let negative values indicate a decrease...

Starting from rest, a 0.0463-kilogram steel ball sinks into a vat of corn syrup. The thick syrup exerts a viscous drag force that is proportional to the ball's velocity: F_drag = -Cv where C = 0.292 N- s/m is a constant related to the size and composition of the ball as well as the viscosity of the syrup. Find the rate at which gravitational energy is converted to thermal energy once the ball reaches terminal velocity.

2. A block of 3 kg is sitting at rest on an incline of 10 degrees. A constant pushing force of 40 N is applied in the uphill direction for 1.3 seconds. The incline also provides a constant friction force of 20 N. Use the impulse-momentum approach to calculate how long the block will continue to slide before it comes to a stop on the incline.
