The aorta in an average adult has a cross-sectional area of 2.0 cm^2. calculate the flow rate of blood of 1.0 g/cm^3 in the aorta if the flow speed is 43 cm/s. answer in units of g/s. (i did this part and the correct answer is 86) assume that the aorta branches to form a large number of capillaries with a combined cross-sectional area of 2.9 × 10^3 cm^2. what is the flow speed in the capillaries? answer in units of cm/s.

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?
