Question

The distance d of a particle moving in a straight line is given by d(t) = 2t3 + 5t – 2, where t is given in seconds and d is measured in meters. Find an expression for the instantaneous velocity v(t) of the particle at any given point in time.

Answer 1

Answer:

Step-by-step explanation:

hello,

$v(t)=\dfrac{d(t)}{t}=2t^2+5-\dfrac{2}{t}$

hope this helps

Answer 2

Answer:

6t^2 + 5

Step-by-step explanation:

i took the test and somehow got it correct:)
