An automobile moves on a road with a speed of
. The radius of its wheels is 0.45 m and the moment of inertia of the wheel about its axis of rotation is
. If the vehicle is brought to rest in 15 s, the magnitude of average torque transmitted by its brakes to the wheel is
Text Solution
Verified by ExpertsThe correct answer is:
A
As velocity of an automobile vehicle,

Angular velocity of a vehicle,

So, angular acceleration of an automobile,

Thus, average torque transmitted by its brakes to wheel
