Answer:
The average force exerted on the window due to two snowballs is 6 N
Explanation:
Given:
Mass of snowballs Kg
Velocity of snowball
For finding the average force,
Force is equal to the change in momentum,
Here, final velocity is zero so we write,
Where sec
N
Above value of force is due to one ball, but here given in question there are two ball,
N
Therefore, the average force exerted on the window due to two snowballs is 6 N
I believe it would be 2.5 meters a second
