Question

The displacement of a particle is given by x = (t +3)^2 where x is in metres and t in seconds. The distance covered by the particle in first 2 seconds is
(a) 24m
(b) 18m
(c) 25m
(d) 11m

Answer 1

Answer:

We have

x= (t+3)^2

where x is in metres and t in seconds.

Explanation:

So the distance covered by the prticle in first 2 seconds is

putting t = 2 in the given equation:

x =(t+3)^2

x=(2+3)^2

x =(5)^2

x= 25 m

Hence option C is correct.
