A 7.80-g bullet moving at 570 m/s strikes the hand of a superhero, causing the hand to move 4.40 cm in the direction of the bullet's velocity before stopping.

The average force is 28797.95 N.

Explanation:

Given that,

Mass of bullet = 7.80 g

Speed = 570 m/s

Distance = 4.40 cm

Suppose Use work and energy considerations to find the average force that stops the bullet.

We need to calculate the average force

Using work energy theorem

Put the value into the formula

Hence, The average force is 28797.95 N.
