12 x sqrt(1.4)

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

wouldnt t= 1.42?

anonymous · Answer

no, because it's t^2 = 1.42

anonymous · Answer

Okay, could you type that out please?

anonymous · Answer

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