The third stage of a rocket is injected by its booster with a velocity u of 13180 km/h at A into an unpowered coasting flight to B. At B it rocket motor is ignited when the trajectory makes an angle of 25° with the horizontal. Operation is effectively above the atmosphere, and the gravitational acceleration during this interval may be taken as 8.97 m/s2, constant in magnitude and direction. Determine the time t to go from A to B. (This quantity is needed in the design of the ignition control system.) Also determine the corresponding increase h in altitude. Answers: t= h = 158.03 122.14 43° Horiz. S km -25° -Horiz.

The Sun orbits the center of the Milky Way galaxy once each 2.60 × 108 years, with a roughly circular orbit averaging 3.00 × 104 light years in radius. (A light year is the distance traveled by light in 1 y.) Calculate the average speed of the Sun in its galactic orbit in m/s.
A rocket fired vertically up from the north pole achieves a velocity of 28 000 km/h at an altitude of 376 km when its fuel is exhausted. Calculate the additional vertical height h reached by the rocket before it starts its descent back to the earth. The coasting phase of its flight occurs above the atmosphere. Consult Fig. 1/1 in choosing the appropriate value of gravitational acceleration and use the mean radius of the earth from Table D/2. (Note: Launching from the earth’s pole avoids considering the effect of the earth’s rotation.) determine h in km
Two ships leave port at the same time, one ship A sailing in the direction N20degreesW at a speed of 20 mi/hr and the second ship B sailing in the direction S70degrees W at the same speed as A. After one hour, find a) the exact value of the distance between the two ships, b) the bearing from ship B to ship A.
A ship bearing N 30-degrees W moves 3 hours at 17 miles per hour. It then turns 50 degrees starboard (to the right) to continue for 4 hours at 21 miles per hour. Finally the ship turns to a bearing of S 20-degrees E and travels for 1 hour at 12 miles per hour. Where is the ship's final location relative to its start?

A skier leaves the ramp of a ski jump with a velocity of υ = 10.0 m/s at θ = 15.0° above the horizontal as shown. The slope where she will land is inclined downward at Φ = 50.0°, and air resistance is negligible. Find (a) the distance from the end of the ramp to where the jumper lands and (b) her velocity components just before the landing. (c) Explain how you think the results might be affected if air resistance were included.

A jet plane is observed 400 ft above the ground and is flying 180 mph to the West. A man jumps out of the plane creating a projectile motion and recorded that he is descending at a constant velocity of 6 ft/s after he reached an observable distance from the ground. If the man is to reach the ground 37 seconds after his immediate jump off the plane, determine the range from the initial position of the plane to the target landing of the man in the ground.
