HELP ASAP TIMED TEST An ball with a mass of M is launched off of a building of height h at an angle of Θ. The highest point in the ball's trajectory is Point P and Point Q is level with the launch height. Ignoring all effects of air resistance, what would the total mechanical energy be equal to at Point Q for the ball-Earth system?

a
1/2Mvoy2 + 1/2Mvox2

b
Mgh + 1/2Mvo2

c
Mgh
d
1/2Mvox2

The mini-refrigerator fire was most likely caused by what type of wiring?

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

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
