1. A physics teacher stands at the edge of a cliff at Canyonlands National Park. The teacher wants to know how high above the base of the cliff he is, so, making sure there are no hikers below drops a large rock over the edge of the cliff. His friend stands at the bottom of the cliff and records the time as 5.8 seconds to reach the ground. How high is the cliff?

Why are graphs useful when interpreting data

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
