A 1500 kg rocket is tobe launched with an initial upwardspeed of 50.0 m/s. In order to assistits engines, the engineers will startit from rest on a ramp that rises 53°above the horizontal (Fig.).At the bottom, the ramp turnsupward and launches the rocketvertically. The engines provide aconstant forward thrust of 2000 N,and friction with the ramp surfaceis a constant 500 N. How far fromthe base of the ramp should therocket start, as measured along the surface of the ramp?

Akagi was a Japanese aircraft carrier used during World War II. The upper flight deck sloped slightly fromamidships toward the bow and toward the stern to assist landings and takeoffs for the underpowered aircraft of that time. Assumea 5 m drop from amidship to the bow. Assume the Japanese Nakajima Ki‐84 plane could takeoff in a length of about 58 m at a speedof 31 m/s. The mass of the plane is 3600 kg fully loaded with gasoline. What force is the engine required to produce for takeoff?Ifthe deck were not sloped, what force would the engines require for takeoff?

. In the movie The Rocketeer, a teenager discovers a jet-powered backpack in an old barn. The backpack allows him to fly at incrediblespeeds. In one scene, however, he uses the backpack to rapidly accelerate an old pickup truck that is being chased by “bad guys.” Hedoes this by bracing his arms against the cab of the pickup and firing the backpack, giving the truck the acceleration of a drag racer. Isthe physics of this scene “Good,” “Bad,” or “Ugly”? Explain.
