Question

A boy of mass 42.7 kg is initially on a skateboard of mass 2.00 kg, moving at a speed of 10.2 m/s. The boy falls off the skateboard, and his center of mass moves forward at a speed of 11.1 m/s. Find the final velocity of the skateboard.

Step 1

The initial momentum \( p_{\text{initial}} \) can be calculated using the formula: \[ p_{\text{initial}} = (m_{\text{boy}} + m_{\text{skateboard}}) \times v_{\text{initial}} \] Where: - \( m_{\text{boy}} = 42.7 \, \text{kg} \) - \( m_{\text{skateboard}} Show more…
