A golf ball is hit from ground level with a vertical velocity of {U_v} m.s-1 and a horizontal velocity of {U_h} m.s-1.

", "advice": "

First consider the problem vertically:

\n

u={U_v}

\n

a=-9.81

\n

v=0

\n

t=?

\n

s=?

\n

Use v=u+at and rearrange so t=(v-u)/a

\n

Now consider horizontally:

\n

u={U_h}

\n

a=0

\n

v=?

\n

t={t}

\n

s=?

\n

Use s=ut+0.5at^2
