Car A, of mass 9300 kg travels at 25 m/s in the +x direction andcollides with Car B, moving towards Car A at -15 m/s (in the -xdirection). The two cars stick together and move off with speed 6.0m/s in the +x direction the collision is inelastic.

a) use the conservation of momentum to determine the mass of CarB.

b) after sticking together the cars slide some distance beforecoming to rest. Assuming that friction between the wheels and theroad is the only force acting determine the work done by thefrictional force.

c)The distance traveled by the cars after the collision wasmeasured to be 12 m. Use the work-energy princciple to determinethe magnitude and direction of the frictional force acting

d) calculate the coefficient of friction of the surface

The two guide rails for the elevator shown each exert a constant friction force of 100 N on the elevator car when the elevator car is moving upward with an acceleration of 2 meters per second squared.

The pulley has negligible friction and mass. Assume g = 10 m/s2. 

a. Draw and label all forces acting on the elevator car. Identify the source of each force.

b. Calculate the tension in the cable lifting the 400-kilogram elevator car during an upward acceleration of 2 m/s2. (Assume g = 10 m/s2)

c. Calculate the mass M the counterweight must have to raise the elevator car with an acceleration of 2 m/s2.

The front brake pads on your car wear out faster than the rearbrakepads; in fact, some cars are specifically designed with largefrontbrake pads because of this. This results from the fact thatwhen acar is braking the magnitude of the friction force acting onthefront wheels of the car is larger than the magnitude of thefrictionforce acting on the rear wheels of the car. Consider a carthat hasa mass of 1500 kg that is decelerating (by using thebrakes) at arate of 0.25 g. The distance between the front andrear axles is 2.8m and the center of mass of the car is directlyin-between the twoaxles at a height of 0.6 m above the ground.What is the ratio ofthe force of friction acting on the fronttires to the force offriction acting on the rear tires? Assumethat the coefficients offriction between the tires and the roadare the same for all tiresand, for simplicity, assume that the caris skidding as itdecelerates.
