A 1000 kg car is pulling a 300 kg trailer. Together, the car and the trailer move forward with an acceleration of 2.15 m/s^2. Ignore any force of air drag on the car and all the friction forces on the trailer. Determine (a) the net force on the car, (b) the net force on the trailer, (c) the force exerted by the trailer on the car, and (d) the resultant force exerted by the car road *

If the solid object shown is in equilibrium, the condition of equilibrium is expressed mathmatically as  FR = F1 + F2 + F3 = 0, where  FR is the resultant force.                                   and  (MR)o = M1 + M2 = 0, where  is the resultant moment about point O.

A skater of mass 8000 g is carrying a box of mass 5 kg. The skater has a speed of 6 m/s with respect to the floor and is gliding without any friction on a smooth surface. a. Find the momentum of the box with respect to the floor. b. Find the momentum of the box with respect to the floor after she puts the box down on the frictionless skating surface.

1. A block resting on a horizontal ground weighs 80 N and inclined force with a slope of 5V:12H is applied to the block. Determine the force that will give the block a velocity of 12 m/s after traveling a distance of 40 m. Coefficient of kinetic friction is 0.26.

Rear Raised Standard 0.6 m 0.4 m 1.3 m 1.6 m 1.3 m 1.6 m Car image from YouTube.com Newton's Laws (Rigid Bodies): In an attempt to make her car accelerate faster, a drag racer has raised the rear of her car to increase the centre of gravity by 0.2 m. The shift in the horizontal location of the centre of gravity is negligible. The car has a mass of 1600 kg and the coefficient of friction is 0.3. The car is rear wheel drive. The front wheels roll freely. Neglect the mass of the wheels. Neglect the suspension deflection. Assume the front wheels stay on the ground. What is the change in maximum acceleration as a percentage taking the unraised car as the reference?

1. A boy in a wheelchair (total mass 50.0 kg) has a speed 1.40 m/s at the crest of a slope 2.60 m high and 12.4 m long. At the bottom of the slope his speed is 6.20 m/s. Assume air resistance and rolling resistance can be modeled as a constant friction force of 41.0 N. Find the work he did in pushing forward on his wheels during the downhill ride.
