A marksman fires a practice round from A toward a target B. If the target diameter is 140 mm and the target center is at the same
altitude as the end of the rifle barrel, determine the range of "shallow" launch angles for which the round will strike the target.
Neglect aerodynamic drag and assume that the round is directed along the vertical centerline of the target. (Note: The word "shallow"
indicates a low-flying trajectory for the round.)

You are a visitor aboard the New International Space Station, which is in a circular orbit around the Earth with an orbital speed of ?o=2.45 km/s�o=2.45 km/s . The station is equipped with a high velocity projectile launcher, which can be used to launch small projectiles in various directions at high speeds. Most of the time, the projectiles either enter new orbits around the Earth or eventually fall down and hit the Earth. However, as you know from your physics courses at the Academy, projectiles launched with a sufficiently great initial speed can travel away from the Earth indefinitely, always slowing down but never falling back to Earth.
With what minimum total speed, relative to the Earth, would projectiles need to be launched from the station in order to "escape" in this way? For reference, recall that the radius of the Earth is ?E=6370000 m�E=6370000 m, the mass of the Earth is ?E=5.98×1024 kg�E=5.98×1024 kg , the acceleration due to gravity on the surface of the Earth is ?=9.81…
In the figure here, a small, solid, uniform ball is to be shot from point P so that it rolls smoothly along a horizontal path, up along a ramp, and onto a plateau. Then it leaves the plateau horizontally
to land on a game board, at a horizontal distance d from the right edge of the plateau. The vertical heights are h,
5.0 cm and h,
1.60 cm. With what speed must the ball be shot at point P for it
to land at d = 6.5 cm?

The arm spins up in a large vacuum chamber, and, at the proper instant, the projectile is released. The tangential velocity imparted to the projectile propels the projectile vertically to an altitude of 61 km where small rocket motors fire to place the payloads into the proper orbit. Since the rockets aren't required until the projectile is above most of the atmosphere, the rocket motors can be small and the quantity of fuel carried (which accounts for most of the mass and cost of traditional rockets) minimized. Assume that the projectile launches vertically and neglect air resistance once the projectile leaves the launcher. What is the mimimum velocity required to boost the projectile to 61 km?arrow_forward
