Laws Of Motion Mock Tests

A block of mass 5 kg rests on an inclined plane with an angle of inclination 37°. The coefficient of static friction is 0.8. The frictional force acting on the block is: (Take g = 10 m/s², sin 37° = 3/5, cos 37° = 4/5)

A block of mass 5 kg is at rest on a rough inclined plane at 37° to the horizontal. The frictional force acting on the block is: (g = 10 m/s², sin 37° = 0.6, cos 37° = 0.8)

A stone is tied to a string of length 1 m and whirled in a vertical circle. The minimum velocity at the lowest point to complete the circle is: (g = 10 m/s²)

A block slides down a frictionless inclined plane of angle 30°. The acceleration of the block down the plane is: (g = 10 m/s²)

Two blocks of masses 5 kg and 3 kg are connected by a light string passing over a frictionless pulley. The acceleration of the system is: (g = 10 m/s²)

A car of mass 1000 kg moves on a circular track of radius 40 m. If the coefficient of friction between the tyres and the road is 0.6, the maximum speed with which the car can move without skidding is (g = 10 m/s²):

A block of mass 5 kg rests on a rough inclined plane at an angle of 37° to the horizontal. The minimum force parallel to the incline required to prevent the block from sliding down is: (μ = 0.5, g = 10 m/s², sin 37° = 0.6, cos 37° = 0.8)

A car moving at 36 km/h is brought to rest by applying brakes. If the coefficient of friction is 0.5, the distance covered before stopping is: (g = 10 m/s²)
