Question

displacement on particle s=3tsqaure-6t find velocity at t=1second​

Answer 1

Answer:

The displacement of particle varies with time as S = 3t2 + 2t Find the velocity of the particle at t = 1 sec. (A) 5m/s (B) 2m/s (C) 8m/s (D) 6m/sRead more on Sarthaks.com - https://www.sarthaks.com/394479/the-displacement-of-particle-varies-with-time-as-3t-find-the-velocity-of-the-particle-at-se

Answer 2

Answer:

s=t

3

−6t

2

+3t=4

v=

dt

ds

=3t

2

−12t+3

a=

dt

dv

=6t−12

So, acceleration will be zero at

6t−12=0

t=2sec

Then velocity at t = 3

v=3(2)

2

−12(2)+3

= 12-24+3

v=−9m/s
