Question:

A pártičle is moving eástwards with á velocity of $5 \mathrm{~ms}^{-1}$. In 10 seconds the velocity changes to $5 \mathrm{~ms}^{-1}$ northwards. The average acceleration in this time is

1. $\frac{1}{2} \mathrm{~ms}^{-2}$ towards north

2. $\frac{1}{\sqrt{2}} \mathrm{~ms}^{-2}$ towards north – east

3. $\frac{1}{\sqrt{2}} \mathrm{~ms}^{-2}$ towards north – west

4. zero
