A yo-yo moves in a straight line up and down a 1 m string. As it travels down the string it has a velocity of and a velocity of when returning towards the hand. In order to do certain tricks, the yo-yo stops at different places along the string as shown in the diagram below. The stops of one particular trick, ‘The Mechanic’, are as follows: Hand-2-1-3-1-Hand
Stop 1 is of the way along the string, Stop 2 is of the way along the string. When the yo-yo reaches Stop 3 the string is fully extended.
By indicating your chosen positive direction clearly on the diagram above, state the following in relation to the yo-yo:
(i)
the displacement from the hand once Stop 2 is reached
(ii)
the velocity when travelling between Stop 2 and Stop 1
(iii)
the velocity when travelling between Stop 1 and Stop 3
(iv)
the maximum displacement from the hand
(v)
the displacement from Stop 3 to Stop 1.
