Energy stored= Li^2/2
Therefore L=2(E.S)/i^2
= 0.0013
Answer:
d = 185.26 meters
Explanation:
It is given that,
Launching angle of the projectile, 
Initial speed of the projectile, u = 48 m/s
Let at distance d the projectile hits the ground from the launch point. It is equal to range of the projectile. Its formula is given by :

Substituting all the values in above formula. So, we get :

d = 185.26 meters
So, the distance between the launch point and the point where it hits is 185.26 meters. Hence, this is the required solution.
Answer:
160m/s
