A plane flying horizontally above Earth’s surface at 184 meters per second drops a crate. The crate strikes the ground 30.0 seconds later. What is the magnitude of the horizontal component of

the crate’s velocity just before it strikes the ground? [Neglect friction.] [1 decimal place, no units]

A soccer player kicks a ball with an initial velocity of 24 meters per second at an angle of 27.° above the horizontal. What is the magnitude of the horizontal component of the ball’s initial velocity? [1 decimal place, no units]

2. Vo = 24m/s @ 27deg,
Xo = hor. = 24cos27 = 21.4m/s.
