Motion In A Plane

Question

A particle is moving eastwards with a velocity of 5 m/s in 10 seconds the velocity changes to 5 m/s northwards. The average acceleration in this time is

$fraction numerator 1 over denominator square root of 2 end fraction straight m divided by straight s squared space$ towards north-east
$1 half straight m divided by straight s squared space$ towards north.

zero

$fraction numerator 1 over denominator square root of 2 end fraction straight m divided by straight s squared space$ towards north-west

Solution

fraction numerator 1 over denominator square root of 2 end fraction straight m divided by straight s squared space

towards north-west

straight a with rightwards arrow on top space equals space fraction numerator stack straight V subscript straight f with rightwards arrow on top minus stack straight V subscript straight i with rightwards arrow on top over denominator straight t end fraction space space equals space fraction numerator 5 straight j with hat on top minus 5 straight i with hat on top over denominator 10 end fraction space equals 1 half space left parenthesis straight j with hat on top minus straight i with hat on top right parenthesis therefore straight a space equals space fraction numerator 1 over denominator square root of 2 end fraction ms to the power of negative 2 end exponent space towards space north space west
