You and a friend live 5 miles apart. You hear a clap of thunder from lightning. Your friend hears the thunder 15 seconds later. Write an equation to determine where the lightning occurred. (Assume sound travels at 1100 feet per second. Impose a coordinate system with units in feet. Assume the transverse axis is horizontal and the center, halfway between you and your friend, is the origin.)

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
