Question
need help with the steps of this problem. A skier goes off aski jump at an angle of 10 degrees below the horizontal travelingat 108 meters horizonally and 55 meters vertically beforelanding. a. ignoring frictiona and aerodynamic effects, determinethe speed neeeded by the skier on leaving he ramp. b. olympic jumpers can make such jumps with a jump speedof 23.0 m/s, which is considerably less than the answer in parta. Explain how this is possible. a. ignoring frictiona and aerodynamic effects, determinethe speed neeeded by the skier on leaving he ramp. b. olympic jumpers can make such jumps with a jump speedof 23.0 m/s, which is considerably less than the answer in parta. Explain how this is possible.Explanation / Answer
horizantal distance travelled x = Vx * t x =V cos * t .......eq1 here V = ? t = ? verticle displacement y = Vyt + gt^2 / 2 y = V sin t + g .t^2 / 2 .........eq2 here V = ? and t = ? from eq1 and eq2 we can solve for V and t , time offlight b) velocity of the skier will increase afterjumping off due to the verticle componet of the gravitational forceacting on them velocity of the skier by the time helands Vx = Vx as intial horizatal component and verticle component Vy = Vyt + dt^2 / 2 = V sin * t + g t^2 / 2 . and V = (Vx^2 +Vy^2).Related Questions
