The maximum horizontal range of a projectile is given by the formula R=u^2/g, where u is the initial velocity and g is the acceleration due to gravity. Find the velocity with which a ball can be thrown to have a maximum range of 20 meters when the acceleration due to gravity is equal to 9.8 m/s.

My answer: 20=u^2/9.8
118=u^2
u=10.8

Am I correct?

No, no, no.

20*9.8 is NOT 118, recheck that
