Answer 1

Answer:

the answer and solution is in the above picture

Answer 2

Given:

A point situated on a wheel decelerates obeying the relation w= w′ -a(theta) is counted from t=0

To Find:

graph representing the angular acceleration of wheel

Explanation:

ω = ω' - aθ:

dθ / dt = ω' - aθ

dω / dt = aω₀e ⁻ᵃⁿ aω' - aθ

The graph representing the angular acceleration of the wheel is given below
