Question

29. The position of a particle along x-axis at time t is
given by x = 1 + t
${?}^{2}$
. The distance travelled by
the particle in first 2 seconds is
(1) 1m
(2) 2 m
(3) 2.5 m
(4) 3 m

​

Answer 1

Answer....

position →

x = t + 1

so , at t = 0

x = 1m

at t = 2 sec

x = 2 + 1 = 3m

so , distance travelled

= 3 - 1

= 2m

Option 2 ✔️✔️

Answer 2

Answer:

2

Explanation:

As the particle is moving along x axis so the distance is clearly given by the equation by putting t= 2

So we get x=1+2 =3

But initially it is at 1 m so the distance travelled will be 3-1 =2
