Answer:
(A) The magnitude of its angular acceleration 1.09 x 10⁻³ rad/s²
(B) Time of motion 240.2 s
Explanation:
Given;
final angular speed, ωf = 2.5 RPM
angular distance, θ = 5 rev = 5 x 2π = 10π rad
initial angular speed, ωi = 0
final angular speed in rad/s;

(A) the magnitude of its angular acceleration(rad/s^2);

(B) Time of motion;

Answer:
h = 0.288m
Explanation:
Assume
= Speed of Sue
= Speed of Chris immediately after the push
Sue's KE = 
now she swings this is converted into gravitation at PE of
mg n = 52 × 9.8 × 0.65
= 331.24
= 331.24
So, 
They started at rest by conservation of momentum in case of push off the magnitude of sue momentum and it is equal to the magnitude of Chris momentum in the opposite or inverse direction



Chris kt = 
= 220.827
220.827 = mgh
So, h = 0.288m
