I’ll literally venmo you if you answer this with FULL EXPLANATION so i can understand please !

The speed with which the man flies after hitting the rock is 5.5 m/s

Explanation:

The given parameters are;

The mass of the man, m₁ = 100 kg

The mass of the scooter, m₂ = 10 kg

The initial speed of the man and the scooter, v₁ = 5 m/s

The speed with which the man flies after hitting the rock = v₂

The final speed of the scooter, v₃ = 0 m/s

The momentum = Mass × Velocity and by the principle of conservation of momentum, we have;

The total initial momentum = The total final momentum

The total initial momentum = (m₁ + m₂) × v₁ = (100 + 10) × 5 = 550

The total initial momentum = 550 kg·m/s

The total final momentum = m₁ × v₂ + m₂ × v₃, which gives;

The total final momentum = 100 × v₂ + 10 × 0

By conservation of momentum, the total initial momentum = The total final momentum, we get;

550 = 100 × v₂ + 10 × 0

∴ 550 = 100 × v₂

v₂ = 550 kg·m/s/(100 kg) = 5.5 m/s

The speed with which the man flies after hitting the rock = v₂ = 5.5 m/s

the answer is to check all of them! they all apply well at least i think so!

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
