The English perfected the longbow as a weapon after the Medieval period. In the hands of a skilled archer, the longbow was reputed to be accurate at ranges to 100 m or more. If the maximum altitude of an arrow is less than h = 10 m while traveling to a target 100 m away from the archer, and neglecting air resistance, estimate the speed and angle at which the arrow must leave the bow. Plot the required release speed and angle as a function of height h.

- PRACTICE II Use the worked example above to help you solve this problem. A rocket has a total mass of 1.04 x 105 kg and a burnout mass of 1.07 x 104 kg, including engines, shell and payload. The rocket blasts off from Earth and exhausts all its fuel in 3.86 min, burning the fuel at a steady rate with an exhaust velocity of ve = 4.16 x 10³ m/s. (a) If air friction and gravity are neglected, what is the speed of the rocket at burnout? m/s (b) What thrust does the engine develop at liftoff? N (c) What is the initial acceleration of the rocket if gravity is not neglected? m/s² (d) Estimate the speed at burnout if gravity isn't neglected. m/s EXERCISE A spaceship with a mass of 4.90 x 104 kg is traveling at 5.71 x 10³ m/s relative to a space station.

He plans to face the box-enclosed fan so that the air blast is directed face down through a 1 m diameter balde span area.

By increasing the power to the fan, he plans to increase the blade rpm and air exit velocity until the exhaust provides sufficient upward force to cause the drone to hover in the air.
