Kids are pelting a window with snowballs. On average, two snowballs of roughly 300-g mass hit the window each second, moving horizontally at some 10 m/s. The snowballs drop vertically to the ground after hitting the window.

Required:
Estimate the average force exerted on the window.

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
