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
