(Answered) A a six flag clown ride rotates 05 revss its mass 210kg

Academics

A) A six flag clown ride rotates 0.5 revs/s, its mass = 210kg diameter= 3.6m , a child whose mass=45kg jumps on and land at a point 0.2 m from outer edge.

1. What is the angular speed of this clown ride after the child lands?

B) The angular speed of a helicopter blade fan has increased in 3 seconds from 9revs/s to 12revs/s.

1. Find angular displacement of the blades during the acceleration? (answer in revs)

2. Find the angular acceleration in standard units?
