A car is moving around a circular track with a radius of 250 meters. The car completes one full lap around the track in 90 seconds. What is the car’s angular velocity? Give your answer in radians/sec

Grandfather clocks are designed to have a period of exactly two seconds. Determine the frequency of the pendulum. Give your answer in Hertz.

An the rotating Earth, the points that will have the highest tangential speed are located at

A box with a mass of 5 kg is placed at the top of an inclined plane that is 10 meters long and makes an angle of 30o with the horizontal. The coefficient of kinetic friction between the box and the inclined plane is 0.2. The box is given a slight push and slides down the incline. Determine the time it takes for the box to reach the bottom of the inclined plane.
