Direction of frictional force between wheel of the carand road is

A car turns a corner on a slippery road at a constant speed of 10 m/s. If the coefficient of friction is 0.5, the minimum radius of the arc in meter in which the car turns is

A body of 10 kg is acted by a force of 129.4 N. If g = 9.8 m/sec². The acceleration of the block is 10 m/s².What is the coefficient of kinetic friction

Consider a car moving along a straight horizontal road with a speed of 72 km/h. If the coefficient of kinetic friction between the tyres and the road is 0.5, the shortest distance in which the car can be stopped is [g =10 m/s²) is

A 500 kg horse pulls a cart of mass 1500 kg along a level road with an acceleration of 1 m/s². If the coefficient ofsliding friction is 0.2, then the force exerted by the horse in forward direction is

The maximum speed of a car on a road turn of radius30 m, if the coefficient of friction between the tyres andthe road is 0.4; will be

A block of mass 50 kg slides over a horizontal distance of 1 m. If the coefficient of friction between their surfaces is 0.2, then work done against friction is

On the horizontal surface of a truck (µ = 0.6), a block of mass 1 kg is placed. If the truck is accelerating at the rate of 5 m/sec², then frictional force on the block will be

A vehicle of mass m is moving on a rough horizontal road with momentum P. If the coefficient of friction between the tyres and the road be µ, then the stopping distance is

A body of weight 64 N is pushed with just enough force to start it moving across a horizontal floor and the same force continues to act afterwards. If the coefficients of static and dynamic friction are 0.6 and 0.4 respectively, the acceleration of the body will be (Acceleration due to gravity = g)
