A freight car having a mass of 15 Mg is towed along the horizontal track. If the car starts from rest and attains a speed of 8 m/s after traveling a distance of 150 m, determine the constant horizontal towing force applied to the car. Neglect friction and the mass of the wheels.

If time is measured along the horizontal axis or X-axis then what is measured along the Y-axis in a business cycle?

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.
