Please help! Physics question about impulse, I think they want the answers in vector notation and that’s what I’m having trouble with. The magnitude of the net force exerted in the x direction on a 2.15-kg particle varies in time as shown in the figure below.
Image has the actual problems

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

Aperson standing in a canoe exerts a force of 700 n to throw an anchor over the side. find the acceleration of the canoe if the total mass of the canoe and the person is 100 kg?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
