ok having problems with part b of golf ball problem
47.0 g golf ball is driven from the tee with an initial speed of 52.0 m/s and rises to a height of 25.0 m.
(a) Neglect air resistance and determine the kinetic energy of the ball at its highest point.
J
(b) What is its speed when it is 10.0 m below its highest point?
m/s
I have used
KEi+PEi = KEf+PEf so
52.029= .0235*x^2 + 6.909
solve for x you get x= 50.07993
However this is not right what am i doing wrong?
