Initial velocity = 17.1sin52=17.1 x 0.788

=13.47 m/s.

max height = 9.81

v^2=u^2 + 2as

v^2=0+2*9.81*6.25

v= 11.07 m/s

My answer is wrong.

looks like you calculated max height as 9.25 not 9.81.

Initial velocity = 17.1sin52=17.1 x 0.788

=13.47 m/s.

max height = 9.81

v^2=u^2 + 2as

v^2=0+2*9.81*6.25

v= 11.07 m/s

My answer is wrong.

An extra step, but you correctly got the y component of the velocity. What about the x component?
