1.	In a two dimensional motion,instantaneous speed v_(0) is a positive constant.Then which of the following are necessarily true?
Answer» The average velocity is not zero at any TIME. Average ACCELERATION must always vanish. Displacements is EQUAL time intervals are equal. Equal path lengths are traversed in equal intervals. Solution :In two dimensional motion, if instanttaneous speed is a positive constant then equal path lengths are traversed in equal intervals of time.
