Jack wants to test how fast can superman save him if he jumps of a cliff 180m high. He recorded that after 5 seconds, superman arrives at the cliff and dives to save Jack. Superman leaves the cliff with an initial velocity to give him a push to catch Jack, and later on act on a free fall as Jack is. Compute the initial velocity of superman so he can catch Jack before they hit the ground.

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 –
