#"0 m/s"#

Initial vertical component of velocity is

#"u"_y = 19.6\ "m/s" × sin30 = "9.8 m/s"#

Use equation of motion #"v = u + at"# along vertical direction

#"v"_y = "u"_y + "a"_y"t"#

#color(white)("v"_y) = "9.8 m/s + (– 9.8 m/s"^2 × "1 s)"#

#color(white)("v"_y) = 0\ "m/s"#

It means projectile is at its highest point after #1# second.
