Uniform Circular motion

A car travels around a circular track with a radius of 100 meters at a constant speed of 20 m/s. What is the centripetal acceleration of the car?

A 0.5 kg ball is attached to a string and swung in a horizontal circle with a radius of 1.2 meters at a speed of 5 m/s. What is the tension in the string?

If a satellite orbits Earth in a circular path with a radius of 1.0 x 10^7 meters and takes 24 hours to complete one orbit, what is its tangential speed?

A cyclist is making a turn on a circular track with a radius of 50 meters. If the cyclist’s speed is 8 m/s, what is the magnitude of the centripetal force if the cyclist has a mass of 70 kg?

An object is moving in a circular path with a radius of 10 meters and an angular velocity of 2 rad/s. What is the centripetal acceleration?

A 2 kg object moves in a circle of radius 3 meters with a centripetal force of 12 N. What is the tangential speed of the object?

If the period of an object in uniform circular motion is 10 seconds and the radius of the circle is 15 meters, what is the centripetal acceleration?

A 0.8 kg ball is swung in a circle of radius 2 meters at a speed of 4 m/s. What is the centripetal force acting on the ball?

A car traveling at 15 m/s goes around a curve with a radius of 50 meters. What is the required coefficient of friction between the tires and the road to prevent skidding? (Assume g = 9.8 m/s²)

If the speed of an object in uniform circular motion is doubled, what happens to the centripetal acceleration?
