Answer:
6.40 m/s
Explanation:
Here we have to consider the conservation of energy
Potential energy of a object = Kinetic Energy
Mgh = 1/2 M (v)2
V = root 2gh
V = root 2*10*20.5
V = 6.40 m/s

Explanation:
Answer:
(A) Torque required is 21.205 N-m
(b) Wok done will be equal to 1199.1286 j
Explanation:
We have given moment of inertia 
Wheel deaccelerate from 135 rpm to 0 rpm
135 rpm = 
Time t = 8 sec
So angular speed
and 
Angular acceleration is given by 
Torque is given by torque 

Work done to accelerate the vehicle is
