1. The small rocket engines used in model rockets are rated by the impulse they exert on the rocket. The graph below shows the force exerted by an engine during the 1.0 second from when it is ignited until when the fuel is completely bumed. a) What is the impulse of this rocket engine? F(N) 0.2 0.4 0.6 0.8 1.0 b) One of these engines is put horizontally on a frictionless cart of mass 780 g so that it will accelerate the cart. How fast will the cart be going after the engine has burned all of its fuel? The mass of the engine itself is small enough that we can ignore it.

A communications satellite weighing 10,000 lb, including fuel, was injected from a space shuttle in low orbit around the earth. After the satellite slowly drifted to a safe distance from the shuttle, its engine was operated to increase its speed by 8000 ft/s as the first step in its transition into a geosynchronous orbit. It is known that fuel is released with a relative speed of 13,750 ft/s. Determine the weight of fuel consumed in the process that took place. choices of the correct answer: 7930 lbs 9930 lbs 4410 lbs 5430 lbs 2230 lbs

1. a) A steel ball is dropped from a building's roof and passes a window, taking 0.13 s to fall from the top to the bottom of the window, a distance of 1.20 m. It then falls to a sidewalk and bounces back past the window, moving from bottom to top in 0.13 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 1.93 s. How tall is the building? b) A basketball player grabbing a rebound jumps 74.1 cm vertically. How much total time (ascent and descent) does the player spend in the bottom 10.3 cm? Do your results explain why such players seem to hang in the air at the top of a jump?
