The drive propeller of a ship starts from rest and accelerates at 3.10 x 10-3 rad/s2 for 2.60 x 103 s. For the next 1.30 x 103 s the propeller rotates at a constant angular speed. Then it decelerates at 2.70 x 10-3 rad/s2 until it slows (without reversing direction) to an angular speed of 3.90 rad/s. Find the total angular displacement of the propeller.
An object has a total energy of 5.0 x 10^15 J and a kinetic energy of 2.0 x 10^15 J. What is the magnitude of the object's relativistic momentum

A small remote-control car with a mass of 1.60 kg moves at a constant speed of v = 14.0 m/s in a vertical circle inside the hollow metal cylinder that has the radius of 5.00 m.
A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.877 rad/s. You, with a mass of 70.5 kg, compute the total angular momentum of the system
Computing the kinetic energy, takeoff speed, and kinetic energy per kilogram.
A 240g block on a 60cm-long string swings in a circle on a horizontal, frictionless table at 70rpm.
A car is parked on a steep incline, making an angle of 37.0° below the horizontal and overlooking the ocean, when its brakes fail and it begins to roll. Starting from rest at t = 0, the car rolls down the incline with a constant acceleration of 3...
A bird is flying directly toward a stationary bird-watcher and emits a frequency of 1230 Hz. The bird-watcher, however, hears a frequency of 1260 Hz. What is the speed of the bird, expressed as a percentage of the speed of sound?
