Afuel pump sends gasoline from a car's fuel tank to the engine at a rate of 6.55x10-2 kg/s. the density of the gasoline is 740 kg/m3, and the radius of the fuel line is 2.67x10-3 m. what is the speed at which gasoline moves through the fuel line?

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
