Initial velocity of both snowball is 29.3 m/s
first snowball launch angle
Considering motion of snowball to be projectile
range is given by


R=70.87 m-----1
If second snowball is thrown at an angle of \phi

------2



or 
Thus
Answer:

Explanation:
From the question we are told that:
Mass m=0.40
Radius r=1.8m
Angle Beneath the Horizontal \theta =40 \textdegree
Speed v=5.0m/s
The Tension Angle


Generally the equation for Tension is is mathematically given by
