*42. D In the javelin throw at a track-and-field event, the javelin is launched at a speed of 29 m/s at an angle of 36° above the horizontal. As the javelin travels upward, its velocity points above the horizontal at an angle that decreases as time passes. How much time is required for the angle to be reduced from 36° at launch to 18°?

6 m/s 39° 1 m 1. A cat jumps off a dresser that is 1 m high. The initial velocity of the cat is 6 m/s at an angle of 39° above the horizontal. How far out from the edge of the dresser does the cat strike the floor? Show your calculations. Refer help sheets next page.

An arrow is shot from a height of 1.75 m toward a cliff of height H. It is shot with a velocity of 32 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 3.65 s later.a. what is the maximum height reached by the arrow along its trajectory in meters?b. what is the arrows speed just before hitting the cliff in m/s?

a. A football player kicks a ball at an initial velocity of 15 m/s at an angle of 30° with horizontal. Find the time of flight, range, maximum height, and velocity components at t = 0, at mid-range and at impact.
