Acceleration 79164

A skier goes down a slope 66 m long in a uniformly accelerated motion in 10 seconds. With what acceleration was it moving, and what is the slope of the slope?

Correct answer:

a =  1.32 m/s2
α =  7.733 °

Step-by-step explanation:

s=66 m t=10 s  s = 21 a t2  a=t22 s=1022 66=1.32 m/s2
g=9.81 m/s2  sin α = a:g  A=arcsin(a/g)=arcsin(1.32/9.81)0.135 rad  α=A  °=A π180   °=0.135 π180   °=7.733  °=7.733=7°4359"
