1) Angie of incidence is equal to the angle of reflection
2) The nornal ray, reflected ray and the incident ray all lie in the same plane
<span>Time until a stone hits the ground :t=8s. Initial velocity of the stone:vi=0m/s. We have to calculate the height of the ledge. Formula for this is: h=vi * t + g*t^2*2, where g=9.81 m/s^2. h=g*t^2/2. h=9.81 m/s^2*(8s)^2/2, h=9.81 m/s^2*64 s^2/2, h=9.81*32m, h=313.92 m. Answer: The ledge is 313.92 m tall. </span>
Answer:) Calculate the acceleration of a skier heading down a. 10.0º slope, assuming the coefficient of friction for waxed.
Explanation:
I believe this is right I'm not sure so if I'm rong let me know please.
Net Force = Applied Force - Friction
Fnet = (22.8N) - (2.3N)
Fnet = 20.5N
