Problem 19E

Problem 19E

Two falling balls The multiflash photograph in the accompanying figure shows two balls falling from rest. The vertical rulers are marked in centimeters. Use the equation s = 490t2 (the freefall equation for s in centimeters and t in seconds) to answer the following questions.

a. How long did it take the balls to fall the first 160 cm? What was their average velocity for the period?

b. How fast were the balls falling when they reached the 160-cm mark? What was their acceleration then?

c. About how fast was the light flashing (flashes per second)?

Step-by-Step Solution:

Solution

Step 1 of 4:

In this problem, we have to find the velocity, acceleration and time by using given graph.

Given that

First find the and 

(a) In this step we have to find the average velocity for the period.

First find the how long did it take the balls to fall the first 160 cm
