A 5 kg block rests on a rough horizontal table. A rope is attached to the block and is pulled with a force of 11N to the left. As a result, the block accelerates at 2 m/s2. The coefficient of
kinetic friction between the block and the table is (round to the nearest hundredth)

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?

2kg of refrigerant 134a undergoes a polytropic process in a piston-cylinder assembly from an initial state of saturated vapor at 2 bar to a final state of 12 bar, 80 degree c. a)determine the work for the process in kj. b)sketch the process on a p-v diagram.

Which type of reaction is shown in this energy diagram ?
