Question

an aeroplane flying with uniform speed 500m/s in a circular path. the change in velocity after half circle

Answer 1

we know that after covering half of the circle the direction of the aeroplane in a circular motion would be anti parallel to each other show the angle velocity at the two spots is 180 degree if the velocity at point A 500 metre per second towards negative x axis x axis then the velocity point B would be 500 m per second towards positive x-axis x axis then change in velocity after half circle is final minus initial velocity that is
it equals to 500-(-500)=1000m/s
