Explanation:
First, the instant associated to the angular displacement is:
Roots of the second-order polynomial are:
Only the first root is physically reasonable.
The angular velocity is obtained by deriving the angular displacement function:
The angular acceleration is obtained by deriving the previous function:
The resultant linear acceleration on the rim of the disk is:
Answer:
0.88752 kgm²
0.02236 Nm
Explanation:
m = Mass of ball = 1.2 kg
L = Length of rod = 0.86 m
= Angle = 90°
