Three blocks A, B and C are placed on a horizontal frictionless surface and are connected by chords between A, B and C. Determine the tension between block B and C when a horizontal tensile force is applied at C = 6.5 N. Masses of blocks are A = 1.2 kg, B 2.4 kg, and C = 3.1 kg.

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.

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

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?
