Question

V=2t²-4t find acceleration, at t=3s​

Answer 1

Answer:

8m/s²

Explanation:

We see that V is given as a function of time.

V=2t²-4t

as you must know that acceleration is the derivative of the function of velocity.

therefore

acceleration (a)=d(2t²-4t)/dt

therefore

a=(2×2t)-4

a=4t-4=4(t-1)

so acceleration at t=3s is

=4(3-1)=8m/s²
