Question

A car of mass m1 and a trailer of mass m2 are parked on a slope that makes an angle of θ with respect to the horizontal. The car is held in place by a force of static friction from its tires. The wheels on the trailer are free to rotate, have no brakes, and have zero rolling friction. What is the tension in the towbar that connects the car to the trailer?

Answer 1

`T=m_2 gsin\theta`

Step-by-step explanation:

The tension, T of the tow bar is given by

`T=m_2 gsin\theta + m_2 a` for the lower side

Where m is mass,
`\theta` is angle of inclination and a is acceleration

Since when in a stationary state there is no acceleration then the formula can be written as

`T=m_2 gsin\theta`
