Problem 5a

Given information

Given:- The ball is thrown into the air with a velocity of 40 ft/s, its height in feet   seconds is defined by an equation  .

To find :- Finding the average velocity means find the slope of the secant line of the curve .

Step-by-step explanation

Consider the height of the ball given by the equation .

First find the height of the ball at time as follows:

Need to find the average velocity for the time period beginning when  and lasting at 0.5 s, 0.1s, 0.05 s, 0.01 s.

Find the formula for the average velocity in the time interval .
