Asked by Danvi

the horizontal range of a projectile is 4a. It passes a tower that height a/2 when the horizontal range was a. What is the projectile velocity and projectile angle.
Answered by drwls
"Range" is how far the projectile travels when it hits the ground

The horizontal range cannot be both 4a and a. Do you mean the height was a/2 when it had travelled a distance a?
