When its engine supplies a force of 506 kg-wt, a car of mass 912 kg moves with constant velocity up a hill of inclination . If the total resistance to the car’s motion is of its weight, what is the angle of inclination, ? Give your answer to the nearest minute.
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 m/s2.
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 .
In a factory, boxes are transferred from one area to another via a rough inclined slope of length 13 m and height 12 m. The boxes are released from rest at the top of the slope and left to slide down freely. Given that the coefficient of friction between the plane and a box is 0.27, find the speed of a box when it reaches the bottom of the slope. Take the acceleration due to gravity .
