Lorenzo is an astronaut, floating in space. Their rocket is powered by throwing rocks out of a hole in the back of the spaceship. The inertial mass of Lorenzo and their rocket together is 391 kg. Lorenzo also (in addition to the rocket and the person) has two 27 kg rocks on board. They are initially at rest. Define an x-axis to point from the back of the rocket to the front. Lorenzo throws the first rock, and then they are moving with velocity component v = 24 m/s. Then Lorenzo throws the second rock out of the back and they are moving with velocity component v = 49 m/s. Part 1 (a) What is the total momentum of the system? Ptotal number (rtol=0.05, atol=1e-08) Part 2 kg.m/s (b) With what velocity along x is the first rock Lorenzo threw moving through space? Vflx = number (rtol=0.05, atol=1e-08) Part 3 m/s (c) with what velocity along x is the second rock Lorenzo threw moving through space? Vf2x = number (rtol=0.05, atol=1e-08) m/s

You can see that you are in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out the window you determine that the rocket is accelerating upward at 8.26 m/s^2. When you drop a ball from a height of 1.81 m, it hits the floor 0.275 s later. What is the value of g for the alien world below you? 48.7 m/s^2 59.4 m/s^2 39.6 m/s^2 57.7 m/s^2

Kyle, a 95.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.538 meters off the ground. He hits the ground 0.0333 metersaway from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball traveling? ball's speed: ? m/s

Dave with a mass of 60 kg goes tubing down a 20 m long hill that has an angle off the horizon of 25º. (Gravity applies) a. He gets a push from the bottom of the hill, so his initial velocity is 2 m/s. How far up the hill will he go before stopping? (there’s no friction) b. He goes back down the hill and then his friend Jill tries to pull him on the tube across a small patch of grass (μk=0.30). If she is pulling parallel to the ground at constant 5 m/s for 5 sec how much power does she expend? c. After climbing back uphill, Dave decided to roll down the hill instead.

An aging coyote (m = 42.1 kg) cannot run fast enough to catch a roadrunner (m = 16.3 kg). He purchases a set of jet-powered roller skates, which proved a constant horizontal acceleration of 15.2 m/s2. The coyote starts at rest 73.2 m from the edge of a cliff at the instant the roadrunner zips past in the direction of the cliff. Hint: their initial positions at the top of the cliff are the same. a. Determine the minimum constant speed the roadrunner must have to reach the cliff before the coyote. b. At the edge of the cliff, the roadrunner escapes by making a sudden turn, while the coyote continues straight ahead. The coyote’s skates remain horizontal and continue to operate while he is in flight, so his acceleration while he is in the air is (15.2i – 9.80j) m/s2. The cliff is 127 m above the flat floor of the desert. Determine how far from the base of the vertical cliff the coyote lands. c. Determine the components of the coyote’s impulse upon impact.
