ᴍᴀxɪᴍᴜᴍ ʜᴇɪɢʜᴛ -

${v}^{2} = {u}^{2} - 2gh$

ᴠᴇʀᴛɪᴄᴀʟ ᴄᴏᴍᴘᴏɴᴇɴᴛ ɪɴɪᴛɪᴀʟ ᴠᴇʟᴏᴄɪᴛʏ -

$u \times \sin(30) = 30 \times ( \frac{1}{2} ) = 15m {s}^{ - 1} \\ h = \frac{ {u}^{2} }{2g} = \frac{15 \times 15}{2 \times 9.8} = 11.5m {s}^{ - 1}$

ʟᴇᴛ ᴠ = 0

ᴛʜᴇɴ ᴛ =

$\frac{15}{9.8} = 1.53m {s}^{ - 1}$

ʀᴀɴɢᴇ ᴏғ ᴛʜᴇ ʙᴀʟʟ,

$u \cos(theta) \times 2 \times 1.53 \\ = 30 \times \frac{ \sqrt{3} }{2} \times 3.06 \\ = 79.5 \: m$
