A box of mass 50kg is placed on an inclined plane. When the angle of the plane is increased to 30°, the box begins to slide downward. Calculate the coefficient of statics friction b/w the plane and box . Draw the free body diagram .

A bullet of mass 20g, travelling at a speed of 350m/s, strikes a steel plate at an angle of 30° with the plane of the plate. It ricochet off at the same angle at a speed of 320m/s. What is the magnitude of the impulse that the steel plate given to the pro...

A truck of mass 2000kg moving on a highway experiences an average frictional force of 800N. If it's speed increases from 25m/s to 35m/s over a distance of 500m what is the force generated by the truck .
