Abicyclist maintains a constant speed of 4.00 m/s up a hill that is inclined at 10.0∘ with the horizontal. calculate the work done by the person and the work done by gravity if the bicycle moves a distance of 18.0 m up the hill. the combined mass of the rider and the bike is 82.0 kg. 1) calculate the work done by gravity. (express your answer to three significant figures.)

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

In which of the following cases is work being done on an object? question 2 options: pushing against a locked door carrying a box down a corridor pulling a trailer up a hill suspending a heavy weight with a strong chain

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
