A motor pulls a crate of mass 300 kg with a constant force by means of a light inextensible rope running over a light frictionless pulley as shown above. The coefficient of kinetic friction between the crate and the surface of the inclined plane is 0.19.
1. The parallel and perpendicular components of the force of gravity are a.b x 10c N for the parallel component and d.e x10d N for the perpendicular component . State your value of abcdef. eg. 123456
2. The force of friction acting on the crate is a.b x 10c N. State your value of abc. eg. 123
3. If the cart accelerates up the incline at a rate of 3.15 m/s2, the tension force in the string connecting the crate is a.b x 10c N. State your value of abc. eg. 123
