Question

The correct symbol to represent the speed of an object is

• A. $\raisebox{1ex}{$5m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$
• B. $\raisebox{1ex}{$5m$}\!\left/ \!\raisebox{-1ex}{$p$}\right.$
• C. $5\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s^{-1}$}\right.$
• D. $5\raisebox{1ex}{$s$}\!\left/ \!\raisebox{-1ex}{$m$}\right.$

Answer 1

The correct option is A

$\raisebox{1ex}{$5m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$

Speed:

1. Speed may be defined as.the rate of change of position of an object in any direction.
2. It is a scalar quantity because it has only magnitude and no direction.
3. Mathematically, Speed $\left(v\right)$= distance$\left(d\right)$/time$\left(t\right)$
4. The distance can be measured in meters and time is measured in seconds.
5. So, The correct symbol to represent the speed of an object is $\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$.

Thus the correct option is option A.
