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

answer: b.
