Question

A formula used for calculating velocity is v = žar”.What is a expressed in terms of v and t?A. a=1 = 2B.a=2C. a=;D. a=Your answer

Answer 1

To answer this question, solve the given expression for calculating velocity for a, this way:

`\begin{gathered} v=(1)/(2)at^2 \\ 2v=at^2 \\ (2v)/(t^2)=a \\ a=(2v)/(t^2) \end{gathered}`

The correct answer is B.
