Question

Equation of trajectory of a projectile is a Y=10x-(5/9)x^2

Answer 1

As we are known that range is stay on X axis and Y axis become 0.

Then you must put Y value =0, 0 = 10 x5/9x 2 t5/9x=10 x=10*9/5x=90/5.

Therefore the x=18.

Therefore the range of meter is between hope this helps the student to understand right answer without meeting any trouble of it.
