Use the method of Newton’s 2nd Law to work this problem. If you work the problem correctly using another method, you will only receive half-credit. A truck of mass 750 kg rests on a ramp inclined at an angle of . A cable running from the car to a wall prevents the car from rolling down the ramp.  Find the tension in the cable and the force that the ramp exerts on the truck’s tires.

An object is moving at constant speed. If the mass of the object is quadrupled and the speed stays the same, the kinetic energy

Use the work-energy theorem to work this problem.  If you work the problem correctly using another method, you will only receive half-credit. A 7 kg block moving at on a horizontal, frictionless surface runs into one end of a light horizontal spring of force constant that is fixed at the other end.  Find the maximum compression in meters of the spring.
