What's the answer?
The Hydra 70 rocket is a weapon derived from the 70 mm (2.75 inch) Mk 4/Mk 40 Folding-Fin Aerial Rocket developed by the United States Navy for use as a free-flight aerial rocket in the late 1940s. The rocket uses the Mk 66 universal motor, which has a mass of 6.2 kg. The burn time of the motor is 1.07 s. The velocity of the exhaust from the nozzle is about 1030 m/s. Assuming that the burn...

Free-fall notion 1. A ball is thrown vertically upward at an initial speed of 49 m/s. Assume that the ball leaves the hand when it is 15 m above the ground (about the height of Kirkbride), and that the effects of air resistance can be ignored. Choose your landmark to be the ground; then at t -0, yo- +15 m, Vyo +49 m/s a. 5 pts) How fast is the launch speed in mph? Do you think this is a...
