Consider two frictionless inclined planes with the same vertical height. Plane 1 makes an angle of 30.0° with the horizontal, and plane 2 makes an angle of 60.0° with the horizontal. Mass m1 is placed at the top of plane 1, and mass m2 is placed at the top of plane 2. Both masses are released at the same time.

A rocket of mass 10^5 kg is launched fromthe surface of the Earth. This is a sketch of the rocket as it’s still in Earth’s atmo-sphere. The rocket is undergoing an accel-eration of 3 m/s^2 upward. There is a forceexerted on the rocket from the thrust of itsengines labeled here as FEngine (you can useFE for short). The rocket is still close to theEarth’s surface, so it is subject to Earth’s gravity, and it is also subject to a substan-tial air resistance force. a. Draw a complete free body diagram of the rocket with all forces acting on it, clearlyindicating which direction each forces act. b. What is the weight of the rocket, and what is the net force on the rocket? c. If the force the engine is exerting is FE = 1.8×10^6 N, what is the magnitude of the forceof air resistance? d. What is the work done by the engine as the rocket rises 150 m?

A rocket accelerates by burning its onboard fuel, so its mass decreases with time. Suppose the initial mass of the rocket at liftoff (Including its fuel) is m, the fuel is consumed at rate r, and the exhaust gases are ejected with constant velocity v. (relative to the rocket). A model for the velocity of the rocket at time t is given by the equation m v(t) = -gt - v, In m where g is the acceleration due to gravity and t is not too large. If g = 9.8 m/s2, m = 27,000 kg, r = 160 kg/s, and v = 3,100 m/s, find the following. (a) the height of the rocket (in meters) one minute after liftoff (Round your answer to the nearest meter.) (b) the height of the rocket (in meters) after it has consumed 5,000 kg of fuel (Round your answer to the nearest meter.) m

While skydiving, a brilliant young physics student known affectionately as “Crazy Kaitlin”launches herself horizontally out of an airplane. The plane is flying steadily at 12,500 feetabove the Earth with a horizontal speed of 80 miles per hour. The total mass of Kaitlinand her gear is 75-kg. Assume g = -9.8 m/s2 While free-falling, Kaitlin engages in some aerial acrobatics. At one point, she finds herself rapidly spinning aboutan axis that runs from her head to her feet. If she wants to quickly decrease her rate of spin, the optimum way forher to this is:A) Cup her hands and claw wildly at the air B) Use counter-flagellation forcesC) Fold her arms tightly across her chest to decrease her moment of Inertia.D) Stretch her arms and legs as far outward as possible to increase her moment of Inertia
