2.) An 800.0 kg sports car slows to 13.0 m/s on the highway to check out the wildflowers and is struck from behind by a 1200 kg pick up traveling at 25.0 m/s. the pick up truck and the sports car's bumper lock together after the rear-end collision. calculate the velocity the two vehicles will move off together.

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.
