Three objects, A : (a solid sphere), B : (a thin circular disk) and C : (a circular ring), each have the same mass M and radius R. They all spin with the same angular speed ω about their own symmetry axes. The amounts of work (W) required to bring them to rest, would satisfy the relation

A toy car with charge q moves on a frictionless horizontal plane surface under the influence of a uniform electric field \(\overrightarrow{E}\) . Due to the force q\(\overrightarrow{E}\), its velocity increases from 0 to 6 m/s in one second duration. At that instant the direction of the field is reversed. The car continues to move for two more seconds under the influence of this field. The average velocity and the average speed of the toy car between 0 to 3 seconds are respectively

A moving block having mass m, collides with another stationary block having mass 4m. The lighter block comes to rest after collision. When the initial velocity of the lighter block is v, then the value of coefficient of restitution (e) will be

A toy car with charge $q$ moves on a frictionless horizontal plane surface under the influence of a uniform electric field $E$ . Due to the force $q\,\vec{E}$ , its velocity increases from $0 \,to\, 6 m/s^{-1}$ in one second duration. At that instant the direction of the field is reversed. The car continues to move for two more seconds under the influence of this field. The average velocity and the average speed of the toy car between $0 \,to\, 3$ seconds are respectively
