Which has greater momentum, a 2.0kg hockey puck moving east at 2.5m/s or a 1.3kg hockey puck moving south at 3.0m/s?
To determine which hockey puck has greater momentum, we need to calculate the momentum for each puck. The momentum of an object is given by the formula:
Momentum (p) = mass (m) × velocity (v)
For the first puck, with a mass of 2.0 kg and moving east at 2.5 m/s, the momentum can be calculated as:
Momentum = 2.0 kg × 2.5 m/s = 5.0 kg·m/s
For the second puck, with a mass of 1.3 kg and moving south at 3.0 m/s, the momentum can be calculated as:
Momentum = 1.3 kg × 3.0 m/s = 3.9 kg·m/s
Comparing the two values, we can see that the first puck (2.0kg moving east at 2.5 m/s) has a greater momentum of 5.0 kg·m/s compared to the second puck's momentum of 3.9 kg·m/s.
To determine which hockey puck has greater momentum, we need to calculate the momentum of each puck using the formula: momentum (p) = mass (m) x velocity (v).
For the first hockey puck moving east:
Mass (m1) = 2.0 kg
Velocity (v1) = 2.5 m/s
Momentum (p1) = m1 × v1 = 2.0 kg × 2.5 m/s = 5.0 kg·m/s
For the second hockey puck moving south:
Mass (m2) = 1.3 kg
Velocity (v2) = 3.0 m/s
Momentum (p2) = m2 × v2 = 1.3 kg × 3.0 m/s = 3.9 kg·m/s
Comparing the two values, we can see that the first hockey puck moving east has greater momentum, with a value of 5.0 kg·m/s, while the second hockey puck moving south has a momentum of 3.9 kg·m/s.
