Question

find Instateneous velocity of x= 2t + 3t^2 at t= 2 s​

Answer 1

Answer:

Heyy frnd your answer is :

x = 2t + 3t^2

v = dx/dt = 2+ 6t

Substituting the value of t as 2, we get

v = 2 + 6 × 2

= 14 m/s

So Instateneous velocity of the object ar time t = 2 s is 14 m/s

Answer 2

Answer:

Here's your answer mate..

V=dx/dt

V= d( 3tsquare -2t)/dt

V=6t

Now t=2

V=6*2=12 m/ sec

Hope i helped you
