The velocity of an automobile starting from rest is given by the equation below, where v is measured in feet per second and t is the time in seconds. (Round your answers to three decimal places.)

v(t) = 105t/ 6t + 17

a. Find the acceleration at 5 seconds.
b. Find the acceleration at 10 seconds
c. Find the acceleration at 20 seconds

a. At t = 5 s

b. At t = 10 s

c. At t = 20 s

Step-by-step explanation:

We know that the velocity function is given by

Acceleration is the rate of change of velocity so we take the derivative of the velocity function with respect to time.

a. At t = 5 s

b. At t = 10 s

c. At t = 20 s

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
