Exactly 2.8 s after a cannon-ball is fired into the air from the ground, it is observed to have a velocity v = (8.0 i^ + 4.9 j^)m/s, where the x axis is horizontal and the y axis is positive upward. A) Determine the horizontal range of the projectile
B) Determine its maximum height above the ground
C) Determine the speed of motion just before the projectile strikes the ground.
D) Determine the angle of motion just before the projectile strikes the ground.

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
