Question

29. The position of a particle along x-axis at time t is
given by X = 1 +t-t². The distance travelled by
the particle in first 2 seconds is
(1) 1 m
(2) 2 m
(3) 2.5 m
(4) 3 m​

Answer 1

Answer:

2 M

Explanation:

At t= 0 it is at x= 1m

at t=2 it is at x= -1 (on negative x axis)

therefore total distance is 1 + 1 = 2M
