Answer:
let us use the expression v = ./2gS in both the cases.
a) In the first case g = 9.8 m/s^2 and S = 10.3 m.
So v = 14.21 m/s
b) in the second case, g = 1.64 m/s^2 and S = 4.2 m = 3.71 m/s

Explanation:
Because I took the USA test prep and got it right
Answer:
Explanation:
Case 1
Given,
initial angular speed = 0 rev/s
final angular speed = 2 rev/s
time, t = 7 s
angular acceleration of the washer
using equation of rotational motion
Case 2
Given,
initial angular speed = 2 rev/s
final angular speed = 0 rev/s
time, t = 12 s
angular acceleration of the washer
using equation of rotational motion
total revolution in this case
total revolution of the washer is equal to 20 rev.
