Question

An object with an initial velocity of 4 m/s moves along a straight axis under constant acceleration three sec later it's velocity is 4 m/ s how far did it travel during this time?

Answer 1

12m because a=0m/s2

Intial velocity is 4. Final velocity is 4. Then by using 1 eq. Of kinematics we calculate a=0m/s2. Then s=ut, hence answer is 12m.
