two 75kg rockets, the A-57x and the B-44zc ,are launched directly upward.The force on each rocket due to its engine decreases from 5000 N to 0N over 8.0 S. The force on the A-57X decreases as a linear function of time while the force on the B-44zc decreases as a quadratic function of time.

A 2400-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 1.90 m/s2 and 1.20 s later an upward velocity of 1.50 m/s . Part A) Determine A....

For his engineering project, Fran¸cois built a model rocket of mass m = 0.55 kg simply by using materials he found lying around the lab and blueprints he found on the internet. The rocket’s propulsion is provided by a special battery-powered fan that is able to provide a constant force |Ffan| = 7.0 N – that is, once it is launched in a specific direction, the direction of the fan’s force does not change. The downside is that the rocket...

Two wires are parallel, and one is directly above the other. Each has a length of 38.6 m and a mass per unit length of 0.0267 kg/m. However, the tension in wire A is 47.3 × 102 N, while the tension in wire B is 1.50 × 102 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much...
