Choose the old man out from the following equations of motion.

Options

A. v = u + at
B. `y = (1)/(2) g t^(2)`
C. `s = ut + (1)/(2) at^(2)`
D. `v^(2) - u^(2) = 2as`

Answer

B

Explanation

`y = (1)/(2) g t^(2) ` is the equation of motion for a freely falling body . But other equations are the equations of linear motion .
