Answer:

Explanation:
As we know that the two students are standing on skates
So there is no external force on the system of two students
So we can say that momentum is conserved
So here initially both students are at rest and hence initial momentum is zero
So we have





its because it allows modern astronomers the ability to see farther out and more accuratly
Answer:
8N
Explanation:
the body is subjected to pressure equals to force force inverse to the area of that body given that it is in motion
Answer:
35.20 m
Explanation:
By the law of conservation of energy we have,



where m= mass of the skier, h= 3.00 m
D= horizontal distance=13.9 m
H= maximum height attained
Also, the horizontal distance covered by the skier is
D=vt


thus, height H in terms of D is given by


H=35.20 m
