1. a 70 kg skier moving at 5 m/sec down a slope. what is the skier's momentum? a. 35 (kg m)/sec b. 350 (kg m)/sec c. 75 (kg m)/sec d. 755 (kg m)/sec

B. 350 kg m/s. A skier of 70kg at 5m/s down a slope will have a momentum of 350kg m/s.

The linear momentum or momentum is represented by the letter p and is defined as the product of the mass of a body by its velocity, that is:

p = m · v

Therefore, when a body is in motion it has a non-zero moment. If it is at rest, its moment is zero. In the International System, it is measured in Kg · m / s.

A 70 kg skier moving at 5m/s down a slope will have a momentum:

p = (70kg)(5m/s) = 350kg m/s
