Question

A body starts from rest and accerlarates uniformly with an accerlaration of (a) for time t1 and achieves the maximum velocity. After that it retrads uniformaly with a retardation of v2 and comes to rest in t2. Find the ratio of t1 and t2

Answer 1

A car starts from rest and attains a velocity of 40 metres per second in 20 seconds. it maintains this velocity for 30 seconds and then comes to rest in 25 seconds. 1. sketch the velocity time graph for the motion. 2. Calculate the acceleration of the body. 3. Calculate the ...
