A physics student is attempting to launch a water balloon over his neighbor's fence, which is 2 m tall The student sets up a launcher that will launch a water balloon at 10 m/s at a 53 degree angle above the horizontal. The launcher is 7.5 m away from the fence. Will the water balloon make it over the fence? If so, by how much does it clear the fence? If not, how far below the top of the fence did the water balloon strike the fence?

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

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
