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

Explanation:

hello,

`v(t)=(d(t))/(t)=2t^2+5-(2)/(t)`

hope this helps

Answer 2

6t^2 + 5

Explanation:

i took the test and somehow got it correct:)
