Well, if the golfer has already covered 0.67fraction of the distance to the whole, that equates to 2/3 of the total distance.
if he has already covered 2/3's of the distance, that means that 1/3 is left to go.
and since he was able to go 2/3 of the distance with his inital speed, how...
well here, since you got the problem right already i'll try to explain it better for you, so you understand it and will be able to get it easily the next time you encounter a question like it.
It says that each dot is 0.5s apart(2 frames/second)
so if you see that the distance between the...
this is just a simple motion diagram, so hence
you don't need any values to figure it out. it is totally conceptual. just look at the distance between the dots after the sticky part and you know the time in between those dots.
hope this helps.
this question seems as if it is a conservation of momentum problem.
therefore,
initial momentum (before collison) must be equal to the
final momentum (after collison)
so just equate the two and you should get the correct answer.
hope this helps.
