## Kinematics of Rotational Motion Revision Questions

1) The rotor of an engine having a radius of 21 cm rotates unformly at 300 rot/min. Calculate the distance travelled by rotor's peripheral points during 10 s. Take π = 22/7.

1. 6600 m
2. 66 m
3. 1.32 m
4. 0.66 m

2) The blade of a helicopter rotating at 720 rot/min stops moving in 15 s after it lands and the pilot turns the engine off. What is the angular displacement of any blade's point during this process?

3) A boy turns uniformly around his head a 1.6 m rope at whose edge he has attached a stone. The stone makes 24 rotations in a minute.

What is the value of centripetal acceleration of the stone during this process? Take π = 3.14.

1. 1.64 m/s2
2. 1.024 m/s2
3. 10.1 π m/s2
4. 10.1 m/s2
