Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A merry-go-round starts at rest and builds up to a final angular speed of 0.34 rad/s while rotating through an angular displacement of 1.9 rad. What is its average angular acceleration?
A
B
0.08 rad/s^2
C
0.13 rad/s^2
D
0.18 rad/s^2
Explanation: 

Detailed explanation-1: -Using the same expression above, this would give the merry go round an angular speed of 1.7 rad/s.

Detailed explanation-2: -The merry-go-round is spinning. Therefore, it is a rotational motion problem.

Detailed explanation-3: -A merry-go-round rotates from rest with constant angular acceleration ‘a’.

Detailed explanation-4: -A merry-go-round rotates from rest with an angular acceleration of 1.50 rad/s2 .
