A car is moving in a circular path with a uniform speed. Find the magnitude of change in its velocity when the car rotates through an angle theta |
|
Answer» Solution :Change in velocity `VEC(Deltav)= vec v= vec v- vec u` The magnitude of change in velocity `DELTA v= sqrt(v^(2)+u^(2)-2 UV cos theta)` As the speed is uniform `=|vecv|=|vecu|=v` `:. Deltav=2v SIN ((theta)/(2))` |
