On a dry road, the maximum speed of a vehicle along a circular path is 'V'. When the road becomes wet, the maximum speed becomes V2. If the coefficient of friction of the dry road is 'μ', then that of the wet road is:

The tendency of an object to resist a change in its state of motion is called:

A box of mass 15 kg is kept on the floor of a stationary trolley. The coefficient of static friction between the box and the trolley is 0.12. To keep the box stationary relative to the trolley, the maximum horizontal acceleration (in m/s2) with which the trolley can move is: (g = 10 m/s2)
