Two identical balls roll across the top of a table on parallel paths. One of the balls has to roll down into and up out of a dip in the table. The other ball rolls on the flat all the time. Which ball gets to the far side of the table first, and why?.
(In reply to my thoughts
What i thought was the incline will definitely speed up the ball goinf downhill and then slow it down to its earlier speed when it reches the top.... so it must takeless time...
BUT it also travels a greater distance that the other ball... if this is equal or more or less than makes up for the increase in speed i cant quite say.
