5. A skater with a mass of 65kg is traveling east at 5m/s when she collides with a second skate mass 45kg heading due south at 10m/s. If they stay tangled together, what is their final velocity (speed + direction)?

Step 1
The momentum of an object is calculated by multiplying its mass by its velocity. For the first skater: Momentum = mass * velocity Momentum = 65 kg * 5 m/s Momentum = 325 kg*m/s For the second skater: Momentum = mass * velocity Momentum = 45 kg * 10 m/s Momentum Show more…

A 520-N skateboarder runs east with a speed of 4.5 m/s toward her 3.0-kg skateboard that is moving 6.0 m/s west. and jumps on. What is the final speed and direction of the skateboarder on the board?

A skater with a mass of 76.4 kg is traveling east at 12.2 m/s when he collides with another skater of mass 65.2 kg heading 57° south of west at 5.2 m/s. Assume they stay tangled together after the collision. What is the magnitude of their final velocity? What is their final direction (in °)? (Take 0° to be due West, 90° to be South, 180° to be East, and 270° to be North.)
