Question

An Olympic skier coasts down a slope with an angle of inclinationof 37°. (a) Neglecting friction, how many forces act onthe skier?
1

(b) What is the acceleration of the skier?
2 m/s2

(c) If the skier has a speed of 5 m/s at the top of the slope, whatis his speed when he reaches the bottom of the 35 m long slope?
3 m/s

(c) If the skier has a speed of 5 m/s at the top of the slope, whatis his speed when he reaches the bottom of the 35 m long slope?
3 m/s

Explanation / Answer

(a). normal force and weight component i.e., two forces are acting onskier (b). accleration a = g sin                            = 5.89 m / s ^ 2 (c). Initial speed u = 5 m / s length of the ramp L = 35 m from the relation v ^ 2 - u ^ 2 = 2aL speed at bottom v = [ u ^2 + 2aL]                             = 20.92 m/ s
