A0.199 kg snowball moving west makes an inelastic collision with a 2.89 kg box moving 0.523 m/s west. afterward, they move west at 1.92 m/s. what was the initial velocity of the snowball?m

The initial velocity of the snowball was 22.21 m/s

Explanation:

Since the collision is inelastic, only momentum is conserved. And since the snowball and the box move together after the collision, they have the same final velocity.

Let be the mass of the ball, and be its initial velocity; let be the mass of the box, and be its velocity; let be the final velocity after the collision, then according to the law of conservation of momentum:

.

From this we solve for , the initial velocity of the snowball:

now we plug in the numerical values , , , and to get:

The initial velocity of the snowball is 22.21 m/s.

P.S: we did not take vectors into account because everything is moving in one direction—towards the west.

because of nuclear radiation.

nuclear radiation kills plants, intoxicates water, and ruins dna and other kinds of cells giving certain living things cancer.
