Answer:
Explanation:
First displacement of the particle is given as
= 11 m at 82 degree with positive X axis
so we can say
resultant displacement of the particle after second displacement is given as
r = 8.7 m at 135 degree with positive X axis
so we can say
now we know that
now we have
so we will have
so angle of the second displacement is given as
<u><em>Answer:</em></u>
Momentum of the skier is 350 Kg.m/sec
<u><em>Explanation:</em></u>
<u>Momentum of a body can be calculated using the following rule:</u>
P = m * v
<u>where:</u>
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
<u>Substitute with the givens in the above rule to get the momentum of the skier as follows:</u>
P = m * v
P = 70 * 5
P = 350 Kg.m/sec
Hope this helps :)
