Question

A body is moving along a straight line with initial velocity v0. Its acceleration a is constant. After t seconds, its velocity becomes v. The average velociy of the body over the given time interval is

• A. $\bar{v}=\frac{v^2+{v_0}^2}{2at}$
• B. $\bar{v}=\frac{v^2+{v_0}^2}{at}$
• C. $\bar{v}=\frac{v^2-{v_0}^2}{2at}$
• D. $\bar{v}=\frac{v^2-{v_0}^2}{at}$

Answer 1

Answer: (C)

$\bar{v}=\frac{v^2-{v_0}^2}{2at}$

Answer 2

The correct answer is (C) : $\bar{v}=\frac{v^2-{v_0}^2}{2at}$.
