A car is moving on a horizontal curved road of radius 50 m. If the coefficient of friction between the tyres and the road is 0.34, the approximate maximum safe speed of the car will be: [Take g = 10 m/s2]

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)
