Question

Using the first equation of motion a = ____.

  1. t (v – u)
  2. (v – u)/t
  3. vut
  4. 2as – t

hintHint:

The first equation of motion is the velocity-time relation.

The correct answer is: (v – u)/t


    Using the first equation of motion a = (v – u)/t
    v space equals space u space plus space a t space
v space minus space u space equals space a t space
a space equals space fraction numerator v minus u over denominator t end fraction
