Answer:
Explanation:
As we know that the wheel is rotated at constant angular speed
so here we can say that the angular speed is given as
now the moment of inertia of all passengers is given as
now work done by machine must be equal to kinetic energy of the system
so we will have
Use SUVAT where:
S = distance
U = initial velocity = 30m/s
V = end velocity = 0 m/s
A = acceleration = ?
T = time = 5 secs
then pick out the equation v = u + at
so:
0 = 30 + 5a
-30 / 5 = a
a = -6 m/s^2
