Answer: The speed at which Maya threw the snowball at Max is 20m/s

Explanation:

Given that

Mass of snowball= 1.5-kg.

Mass of Maya= 12kg

Initial speed of Maya=2.5m/s

We use the law of conservation of momentum to calculate the speed of the snowball which depends on its own mass, the mass of Maya who threw the snowball and the initial velocity at which the snowball was thrown by Maya

Ms x Us = Mm x Um

Mass of snowball x Initial speed of Snow ball =Mass of Maya x Initial speed of Maya

1.5kg x Initial speed of Snow ball =12 kg x 2.5m/s

Initial speed of Snow ball=( 12 kg x 2.5m/s) /1.5kg

Initial speed of Snow ball =20m/s
