Question

2) The displacement of a body is defined
x=(t-2)² where & x is in metre and
t is im second. The distance covered in
4 seconds ​

Answer 1

Answer:

X =(t-2)^2 = t^2–4t + 4

v = 2t - 4

Distance covered = integ(|v|dt)

= |t^2–4t|

= 4t - t^2 for t = 0 to 2

= t^2 - 4t for t = 2 to 4

= 8 units
