A roller coaster car (mass = M) is on a track that forms a circular loop (radius = r) in the vertical plane. If the car is to just maintain contact with the track at the top of the loop, what is the minimum value for its speed at that point

A stone, of mass m, is attached to a strong string and whirled in a vertical circle of radius r. At the exact top of the path the tension in the string is 3 times the stone's weight. The stone's speed at this point is given by

What force is centripetal force in the given figure?

Relation between The linear velocity (tangential velocity) ‘v’ and the angular velocity

An athlete weighing 980 N is running a curve at a speed of 5 m𝑠^(−1) in an arc. The radius of curvature of arc is 7 m. Find the centripetal force acting on him. Which force provides the centripetal force?

The magnitude of the centripetal (radial) acceleration is

When the angular velocity is increasing, the angular acceleration vector points -----------.

What is the angle of banking which would allow vehicles to round a curve of 900 ft radius at 40 mph without friction ?

The angle through which an object in rotation moves, measured in degree or radians is -----------.

For an object moving in uniform circular motion, does the velocity change? why?

Circular motion is a specific type of a -------- motion

An object is moving in a COUNTERCLOCKWISE circle at constant speed. What is the direction of the velocity vector at point B?
