Explain centripetal acceleration.

To simulate the acceleration of large rockets , the astronauts are spun at the end of long rotating beam of radius 9.8 m. What will be angular velocity required for generating centripetal acceleration 8 times the acceleration due to gravity ?

A particle of mass 200 g completes one rotation of a circular track of radius 2 m in 21 second. Calculate centripetal acceleration .

For a particle in circular motion the centripetal acceleration is

Angle between radius vector and centripetal acceleration is

A body moving along a circular path of radius r with velocity V, has centripetal acceleration 'a'. If its velocity is made equal to 2V, then its centripetal acceleration is.

An aircraft executes a horizontal loop of radius 1 km with a steady speed of 900 km h^(-1) . Compare its centripetal acceleration with the acceleration due to gravity.

A particle moves in a circle with constant speed of 15 m//s . The radius of the circle is 2 m. Determine the centripetal acceleration of the particle.

A particle moves in a circle with constant speed of 15 m/s. The radius of the circle is 2 m. Determine the centripetal acceleration of the particle.
