A soccer ball is kicked from the roof of a building with a height of 45.0m, near the surface of the Earth, with an initial velocity vi=14.2m/s. The ball exists the surface of the roof moving horizontally. A) How long is the ball in the air?

B)How far away from the base of the building does the ball land?

C) How fast is the ball moving just before it strikes the ground?

D) At what angle does the ball strike the ground? This angle is measured with respect to the horizontal direction.

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Which sound characteristic is not affected by the relative motion of an object
