a guy is throwing pumpkins off a five story (15 meters high) building and wants the messiest result possible (highest velocity impact). a) he first throws a pumpkin downward at 45 degrees below the horizon at 15 m/s. how fast does the pumpkin hit the ground? at what angle does it hit? b) he then throws a second pumpkin upward with the same velocity 45 degrees above the horizon. how fast does the second pumpkin hit the ground? c) which strategy (throwing the pumpkin up or down) results in a higher velocity impact? think about why this might be

A physics book slides off a horizontal table top with a speed of 1.90 m/s. It strikes the floor after a time of 0.460 s. Ignore air resistance.   A) Find the height of the table top above the floor. B) Find the horizontal distance from the edge of the table to the point where the book strikes the floor. C) Find the magnitude of the horizontal component of the book's velocity just before the book reaches the floor.   D)  Find the magnitude of the vertical component of the book's velocity just before the book reaches the floor.   E)  Find the magnitude of the book's velocity just before the book reaches the floor.   F)  Find the direction of the book's velocity just before the book reaches the floor in degrees

An airplane is flying horizontally with speed 1300 km/h (360 m/s ) when an engine falls off. Neglecting air resistance, assume it takes 35 s for the engine to hit the ground A)Find the altitude of the airplane. (Use g=9.8m/s2.). B)Find the horizontal distance the airplane engine falls. C)If the airplane somehow continues to fly as if nothing had happened, where is the engine relative to the airplane at the moment the engine hits the ground?

A ball is thrown horizontally from the top of a building 22m high.the ball strikes the ground at a point 35 m horizontally away from and below the point of release.Air resistant is neglected from this problem.e.what is the speed of the ball just before it strikes the ground?
