Question

Hi! I need help answering calculating the average velocity (ft per second), and instantaneous velocity. Pictures

of the questions are attached along with the table to go by. This question has several parts with different numbers. The table with the t (seconds) and s(t) (feet) are in the first picture and the picture with the actual questions are below. IMG_07921.jpgIMG_07911.jpgIMG_07911.jpg

A car is moving along a straight test track. The position (in feet) of the car, s(t), at various times t is measured, with the results shown to the right. Use the table to a
(a) Find the average velocity from 1 to 3 seconds
The average velocity is fus.
(Type an integer or a decimal.)
(b) Find the average velocity from 3 to 5 seconds.
The average velocity is fu/s.
(Type an integer or a decimal.)
(c) Find the average velocity from 5 to 7 seconds.
The average velocity is fu/s.
(Type an integer or a decimal.)
(d) Estimate the instantaneous velocity at 5 seconds using the formula for estimating the instantaneous rate (with h = 2).
The instantaneous velocity is approximately f/s.
(Type an integer or a decimal.)
Estimate the instantaneous velocity at 5 seconds by averaging the answers for the average velocity in the 2 seconds before and the 2 seconds afterward (that is, the
