Hello what is a major theme of this speech?

f is prop to m1xm2 double m1 double force

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle

98.4 m

explanation:

let s = distance up the plane  

then by conservation of energy  

1/2m(18.3)^2 = mg s sin(10)  

(18.3)^2 = 2g s sin(10)  

s = (18.3)^2/2gsin(10)  

= 98.39564526  

= 98.4 m
