Answer:
Angle of projection from the horizontal will be
Explanation:
We have given that range of the projectile is 10 times the height of the projectile
Let the projectile is projected with velocity u at an angle
Range of the projectile is equal to
And height of the projectile is equal to
Now according to question range is 10 times of height
So
So angle of projection from the horizontal will be
