Question

While skiing, Ellen encounters a ledge that sends her flying horizontally at a rate of 12 m/s. How far away will she land if the ledge is 7 meters high?

Answer 1

12 x sqrt(1.4)

Answer 2

Could you explain a little bit because Im not sure I understand

Answer 3

7 meters high will mean that she will fall 7 meters down.

How much time does this take?

s = 1/2 a t^2
7 = 1/2*9.81*t^2
t = 1.19

horizontal distance = v*t = 12*1.19 = 14.33 meters

Answer 4

wouldnt t= 1.42?

Answer 5

no, because it's t^2 = 1.42

Answer 6

Okay, could you type that out please?

Answer 7

s = 1/2 a t^2
7 = 1/2*9.81*t^2
t^2 = 1.42
t = 1.19
