Question

Two objects A and B both starts with zero initial velocities and accelerations constant a and a respectively.Distance travelled by A during first 2 s is found to be same as distance travelled by B during 4^( th ) second of it's motion.Then - (1) 3a_(1)=5a_(2) (2) 4a_(1)=7a_(2) (3) 5a_(1)=7a_(2) (4) 3a_(1)=7a_(2)​

When an object covers equal distance in equal time interval is called uniform motion, whereas when an object covers unequal distance in equal time interval is called non-uniform motion. Speed: The rate of motion of an object is to find out the distance traveled by the object in unit time is referred as speed.
