A skier (m=59.00 kg) starts sliding down from the top of a ski jump with negligible friction and takes off horizontally. If h = 7.70 m and D = 12.90 m, find H.(adsbygoogle = window.adsbygoogle || []).push({});

I was given a hint to treat the skier as a projectile, so I broke the skier's position into two parts.

yf=yi+vt+1/2gt^2

0=7.70+Vt+4.7t^2

xf=x0+Vt

12.9=0+vt

then solve for t in the x

12.90/vt

so I sub that back in to y

0=7.70+v(12.90/v)-4.7(12.90/v)^2

I get a velocity of 8.89 m/s

am I doing this right
