A ball is hit east from a 10 meter elevated platform with an initial velocity of <50, 0, 30> m/s. A wind blowing to the south produces an acceleration on the ball of -1.2 m/s^2.
a. Find the velocity and position vectors for t ≥0.
b. Determine the time of flight and range of the ball.
c. Determine the maximum height.
d. If you want the ball to land due east of your initial position, determine the correction
angle.

A current in a river is pushing a ship in a direction of 25 degrees north of east with a speed of 12 knots (nautical miles per hour). There is a 7 knots (kn) wind pushing the ship in a direction 80 degrees south of east. Find the velocity vector of the ship vector of the ship relative to the water if the ship is moving due east at a speed of 40 knots (kn) relative to the ground.
