A mountain climber stands at the top of a 20.0 m cliff that overhangs a calm pool of water. She throws two stones vertically downward 1.00 s apart and observes that they cause a single splash. The first stone had an initial velocity of -2.20 m/s. (a) How long after release of the first stone did the two stones hit the water? (Round your answer to at least two decimal places.) (b) What initial velocity must the second stone have had, given that they hit the water simultaneously? (c) What was the velocity of e

Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –
