Answer 1

Answer:

$\huge\bf\purple{answer✏:}$

After another second,

a total of 4 seconds, the velocity will have changed by another - 9.8 m/s

so that the velocity would be ( 0 m/s) + (- 9.8 m/s)

= - 9.8 m/s.

Answer 2

Answer:

Measure the distance the object will fall in feet with a ruler or measuring tape. Divide the falling distance by 16. For example, if the object will fall 128 feet, divide 128 by 16 to get 8. Calculate the square root of the Step 2 result to find the time it takes the object to fall in seconds.
