Q1. A chair of mass 14.0 kg lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 40.0 N directed at an angle of 42.0 degrees below the horizontal and the chair slides along the floor.
By means of Newton's laws, calculate n, magnitude of the normal force that the floor exerts on the chair.

Q2. A 1600 kg car starts from rest at A, coasts 180m through a dip and comes to stop at B after coasting a distance d on level ground. If the rolling resistance is a constant force of 280N, conclude the distance d.
