Question

v=9t*2+2t+9 m/s. if the body starts from x=3m, find the position at t=2s​

Answer 1

MARK BRAINLIEST

v=9t×2+2t+9

=20t+9.

The body starts from 3 metre .

The linear position at 2 second is to be found.

v=20t+9

=20(2)+9

=40+9

=49

V=49, t =2 m.

Now , v=d/t

d=98 metre+3 metre .(refrence origion is 3m before beiggining)

d=101 metre .

Body travelled 101 metres
