Question
A particle is moving eastward with a velocity of 5 m/s. In 10 s the velocity changes to 5 m/s northwards. The average acceleration in this time is
Options
A.zero
B.
m/s2 towards north-east
m/s2 towards north-eastC.m/s2 towards north-west
m/s2 towards north-westD.m/s2 towards north
m/s2 towards northSolution
