Answer : Tension in the line = 936.7 N
Explanation :
It is given that,
Mass of student, m = 65 kg
The angle between slackline and horizontal,
The two forces that acts are :
(i) Tension
(ii) Weight
So, from the figure it is clear that :
Hence, this is the required solution.
The momentum of a moving object is given by:
where m is the mass of the object and v its speed.
In this problem, the ball has a mass of
and its momentum is 
, so we can rearrange the previous equation to find the speed of the ball:
where m is the mass of the object and v its speed.
In this problem, the ball has a mass of
