Question

If the displacement of a particle at any time $t$ is given by $s=ut+\frac{1}{2}a{t}^2$, where $u$ and $a$ are constants. Then the acceleration of particle at any time $t$ will be

• A. $a$
• B. $u+a$
• C. $u$
• D. None

Answer 1

The correct option is A $a$

We know that the first derivative of velocity is acceleration, $\frac{dv}{dt}=a$
