The 1994 Winter Olympics included the aerials competition in skiing. In this event skiers speed down a ramp that slopes sharply upward at the end. The sharp upward slope launches them into the air, where they perform acrobatic maneuvers. In the women's competition, the end of a typical launch ramp is directed 63° above the horizontal. With this launch angle, a skier attains a height of 14.0 m above the end of the ramp. What is the skier's launch speed?
What vertical velocity will get one to 14m?
vvel= g*time solve for time, then put time in
h= vvel*time- 1/2 g time^2
and solve for vvel.
launch speed= vvel/sin63
But there is no time specified
But there was no time specified
vvel= g*time solve for time,
time= vvel/g
put that into
h= vvel*time- 1/2 g time^2
then solve for vvel.
thank you so much for your help
