Question

The unit of the slope of a v-t graph of a body is ___.

  1. m/s 
  2. m/s2   
  3. N
  4. m

hintHint:

m/s²

The correct answer is: m/s2


    The unit of the slope of the v-t graph is ms-2 for acceleration.
    Justification:
    S l o p e space equals space fraction numerator v e l o c i t y space over denominator t i m e end fraction
S l o p e space equals space fraction numerator m over denominator s space cross times space s end fraction space equals space m s to the power of negative 2 end exponent
