Question

A sled and rider, gliding over horizontal, frictionless ice at 4.9{ m m/s} , have a combined mass of 86{ m kg} . The sled then slides over a rough spot in the ice, slowing down to 2.1{ m m/s} What impulse was delivered to the sled by the friction force from the rough spot?

Step 1

The initial momentum of the sled and rider can be calculated using the formula: p = mv where p is momentum, m is mass, and v is velocity. p = (86m kg)(4.9 m/s) p = 421.4m kg/s Show more…
