At what speed must a 10 kN car approach a ramp which makes an angle of 30° with the horizontal an 18 m high at the top such that it will just stop as it reaches the top. Assume resisting force of friction, to be 0.60 kN.

What will be the force of static friction on a crate lying on a horizontal ramp?

A force of 100 N is applied on a crate to push it over 10 m factory floor horizontally and the friction force offered by the contact surface is 70 N then calculate the kinetic energy gained by the crate.

Consider a problem in which a car of the mass ‘m’ is moving on a road tilted at an angle from the horizontal. What will be the normal reaction of the surface?
