A scientist builds a device to measure the speed of a golf ball. The 0.030kg ball is fired into a 0.080kg box that is attached to the edge of a record turntable (mass=0.050kg and radius=0.20m). As a result, the turntable spins.
If the golf ball comes in with a speed of 26.0m/s, calculate the angular velocity of the turntable after the ball is caught.

3. The ballistic pendulum is a device used to measure the speed of a projectile, such as a bullet. The projectile, of mass m, is fired into a large block of mass M, which is suspended like a pendulum. As a result of the collision, the pendulum and projectile together swing up to a maximum height h. Determine the relationship between the initial horizontal speed of the projectile, v, and the maximum heighth

Problem 3 A 60.0-kgrunner runs clockwise around the edge of a horizontal turntable mounted on a vertical, frictionless axis through its center. The runner's velocity relative to the ground has magnitude 2.00 m/s. The turntable is rotating in the opposite direction (counterclockwise) with an angular velocity of magnitude 0.300 rad/s relative to the ground. The radius of the turntable is 2.90 m, and its moment of inertia about the axis of rotation is 80.0 kg m2. Questions 4 and 5...

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
