A particle starts with an initial velocity 2 m/s along the positive x direction and it accelerates uniformly at the rate 1m/s2. Find the following:

(a) Distance traveled by it in the first two seconds
(b) How much time it take to reach the velocity of 5 m/s
(c) How much distance will it cover in reaching the velocity 5 m/s

Expert Answer:

we have

(a) S = ut +1/2 a t2
          = 2  2 + ½   1  (2)2
           =   4 + 2
            = 6m
(b) Time taken to reach the velocity of 5 m/s is:
 v = u + at
5 =  2 + 1  t
t = 3 seconds
(c) Distance covered on reaching the velocity of 5 m/s is:
