Question 1:
A soccer ball is kicked from the ground with an initial speed of 18.0 m/s at an upward angle of 46.3°. A player 53.2 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.
Question 2:
A certain airplane has a speed of 337.4 km/h and is diving at an angle of θ = 33.0° below the horizontal when the pilot releases a radar decoy (see the figure). The horizontal distance between the release point and the point where the decoy strikes the ground is d = 679 m. (b) How high was the release point?
