Problems of finding the no of revolutions per min/sec

The angular velocity of a particle moving in a circle of radius 50 cm is increased in 5 min from 100 revolutions per minute to 400 revolutions per minute. Find the tangential acceleration of the particle.

The angular velocity of a particle moving in a circle of radius 50 cm is increased in 5 min from 100 revolutions per minute to 400 revolutions per minute. Find the tangential acceleration of the particle.

A particle moves in a circle of radius 25 cm at two revolutions per sec. The acceleration of the particle in m//s^(2) is:

A fly wheel of moment of inertia I is rotating at n revolutions per sec. The work needed to double the frequency would be -

A particle moves in a circle of radius 25 cm at two revolutions per sec. The acceleration of the particle in m//s^(2) is:

A tractor has rear wheels with a radius of 1.00 m and front wheels with a radius of 0.250 m. The rear wheels are rotating at 100 rev/min. Find (a) the angular speed of the front wheels in revolutions per minute and (b) the distance covered by the tractor in 10.0 min.
