## Homework Equations

.5mv^2+mgh=.5mv^2+mgh

## The Attempt at a Solution

I first divided to vertical distance by 9.81 to get .81seconds, then 9.50/.81 to get the horizontal velocity, which is 11.72 m/s

I then plugged the information into the above equation for

53*9.81*x=.5*53*11.72^2+53*9.81*8

solving for x i got 15.01 m, which is not correct.
