1. 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 $0.15m{s}^{-1}$ and a velocity of $0.12m{s}^{-1}$ 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 $\frac{1}{4}$ of the way along the string, Stop 2 is $\frac{4}{5}$ 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.
