Assertion: In projectile motion, the acceleration is constant in both magnitude and direction but the velocity changes in both magnitude and direction. Reason: When a force or accelration is acting in an oblique direction to the direction of velocity then both magnitude and direction of the velocity may be changed.

Ram is facing North -west . He turns in clockwise direction by 90^(@) , then 180^(@) in the anti- clock -wise direction and them another 90^(@) in the same direction and the another 90^(@) in the same direction . Which direction is he facing now ?

A car is moving with a speed of 10m s^(-1) , If the east direction taken as x-axis and the north direction as y-axis . Write the velocity vector of car in unit vector notation.If it is moving (a) in the direction of N-E,(b) in the direction of N-W ,(C ) in the direction of S-W , and (d) in the direction of S-E .
