A body weighing 3500N is pushed up a rough inclined plane by a force of 5000N. The angle of inclination is 30deg. and the force is applied horizontally. If the coefficient of kinetic friction is 0.5, calculate the acceleration of the body.

A 1200kg travelling east collides with another 1000kg car travelling north. If they are both travelling at 90km/h and the collision is completely inelastic, find the velocity of the systemafter collision.
