A car of mass tons was initially at rest on a hill inclined at an angle to the horizontal, where . After 100 seconds, its velocity was 21 m/s. Calculate the resistance per ton of the car’s mass. Take .
A body was placed on the top of a rough inclined plane of length 259 cm and height 84 cm. The body started sliding down the plane. Given that the coefficient of friction was 0.29 , find the acceleration of the body. Take .
A small wooden box of mass 11 kg was placed at the top of a rough inclined plane of length 2.25 m and height 1.8 m. Given that it slid down the plane in 1 second, find the magnitude of its acceleration and the magnitude of the friction between the box and the plane. Take the acceleration due to gravity .
