Momentum = mass × velocity
Given:
- Mass of the student (m1) = 59 kg
- Mass of the motorcycle (m2) = 220 kg
- Velocity (v) = 12 m/s (assuming the student and the motorcycle are moving at the same velocity)
Total mass (M) = m1 + m2 = 59 kg + 220 kg = 279 kg
Substituting the values into the formula, we get:
Momentum = (279 kg) × (12 m/s)
Momentum = 3348 kg m/s
Therefore, the total momentum of the physics student and her Harley is 3348 kg m/s.
