Homework Statement
A particle is moving eastwards with a velocity of 5m/s. In 10 seconds, the velocity changes to 5 m/s northwards. What is the average acceleration time? What is the direction of accleration?
Homework Equations
a=v-u/t
The Attempt at a Solution
initial velocity northwards = u = 0 m/s
final velocity northwards = v = 5 m/s
t = 10 s
a = v-u/t= 1/2 m/s^2
Now initial direction = eastwards = 0 degree
final direction = northwards = resultant = 90 degree
therefore, using vector rules, direction of acceleration = north-west = 120 degree
Am I right?
