a leaver raised 500N lode using 200N effort. if load distance and effort distance are 20 cm and 60 cm respectively, calculate mechanical advantage, velocity ratio and efficiency of this lever.​

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

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
