A formula car produces a downward force of 316 N and a drag force of 164.5 N at a velocity of 21 m/s. If a wing with a body area of 2 m2 and a lift coefficient of 0.7 and a drag coefficient of 0.06 is added to the car what is the new total downward and drag forces acting on the car at this velocity

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
