Answer:
The answer is
<h2>158.4 kgm/s</h2>
Explanation:
The momentum of an object when given it's mass and velocity can be found by using the formula
<h3>momentum = velocity × mass</h3>
From the question
velocity = 2.2 m/s
mass = 72 kg
The momentum is
momentum = 2.2 × 72
We have the final answer as
<h3>158.4 kgm/s</h3>

The instant it was dropped, the ball had zero speed.
After falling for 1 second, its speed was 9.8 m/s straight down (gravity).
Its AVERAGE speed for that 1 second was (1/2) (0 + 9.8) = 4.9 m/s.
Falling for 1 second at an average speed of 4.9 m/s, is covered <em>4.9 meters</em>.
ANYTHING you drop does that, if air resistance doesn't hold it back.
