Problem

A particle moves in the

x

y

plane. At

t=0

, it is at

(1\,\text{m},2\,\text{m})

and has velocity

(4\hat{i}+6\hat{j})\,\text{m s}^{-1}

. At

t=4\,\text{s}

, it is at

(6\,\text{m},4\,\text{m})

and has velocity

(2\hat{i}+10\hat{j})\,\text{m s}^{-1}

. In the given time interval, find: (a) Average velocity. (b) Average acceleration. (c) From the given data, can you find the average speed?
