WebThrust is a force that moves an aircraft in the direction of the motion. It is created with a propeller, jet engine, or rocket. Air is pulled in and then pushed out in an opposite direction. One example is a household fan. Drag is the force that acts opposite to the direction of motion. It tends to slow an object.

Assuming that the rocket is moving at a constant speed v upwards, the required power would be P 1 =Tv, as you've stated. The required thrust would be T=mg+F, where F is the friction force. If the speed doubles, but friction does not change, the required thrust will stay the same so the power will double: P 2 =T*2v. gyms with pools in fayetteville ncWebNov 9, 2014 · Assuming you eject 4 pounds/sec at 3200ft/sec you would accelerate you 200 pound weight upward at about 1 g, 32 ft/sec**2. The time t needed to rise 400 ft at 1 g is the solution to 400 = 16* t**2, so t**2 is 25, so t = 5 seconds.
