Answer:
angular acceleration = -18.75 rad/s²
angle = 650 rad
length = 130 m
work done = 24 J
Explanation:
given data
radius = 0.20 m
speed s1 = 200 rad/s
speed s2 = 125 rad/s
time = 4 s
mass = 3 kg
speed = 4 m/s
to find out
angular acceleration, angle and length and work done
solution
we apply angular acceleration formula that is
s2 = s1 + αt
put here value
125 = 200 + α(4)
α = -18.75 rad/s²
angular acceleration = -18.75 rad/s²
and
angle will calculated as
angle = s1(t) + 1/2 × α × t²
angle = 200(4) + 1/2 × (-18.75) × 4²
angle = 650 rad
and
length will be
length = radius × angle
length = 0.2 × 650
length = 130 m
and
work done is calculated as
work done = 1/2 × mv²
work done = 1/2 × 3(4)²
work done = 24 J
