alleryWhich one of the following is the equation for the velocity-time relation?
As = ut + ½at²
Bv = u + at
Cu = v + at
D2as = v² - u²
Answer & Solution
Correct answer: B. v = u + at
1. The first equation of motion relates final velocity to initial velocity and time.
2. It is written as v = u + at, where a is acceleration and t is time.
3. The other forms relate displacement, not directly velocity to time.
