A 45.0kg mass is at the top of an incline that has a vertical height of 16m. As the box slides to the bottom it loses 2630 J of energy through friction. How fast is it moving at the bottom?

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

Acompound machine is also called a machine. a. force b. simple c. complex d. directional

The slope of a velocity time graph over any interval of time gives the during that interval
