A70kg skier moving at 5 m/sec down a slope what is the skier’s momentum

Momentum of the skier is 350 Kg.m/sec

Explanation:

Momentum of a body can be calculated using the following rule:

P = m * v

where:

P is the momentum of the body

m is the mass of the body given as 70 Kg

v is the velocity of the body given as 5 m/sec

Substitute with the givens in the above rule to get the momentum of the skier as follows:

P = m * v

P = 70 * 5

P = 350 Kg.m/sec

Hope this helps :)

the higher the current the higher the mag field around it the higher the influence on the compass

the answer is a. hope this .
