Well?

well?

Am I supposed to measure them myself or what?

d

-/112

How would it ever reach a or b

nobody.

E. It's the only answer.

The answer is 17 because of the parentheses

In most cases D. If the crescent is at the correct angle for the survival of the person in D, then E.

without knowing the mass of the objects or the friction of the surfaces where applicable, what i do see is the angle of the platform the lower object is sitting on. when lifted it will fly to the right, if its mass is smaller than the one above, that is the only thing it will do. the kinetic energy of the rolling object will not stop and instantly transfer through the seesaw to the other one. it will still roll forwards and reach that little ramp. The shape of the rolling object would have to slow it down on the slope for it to stop at that little ramp (the one above the three spikes). All i can say is too little information.
