An athlete's coach told him that muscle times speed equals power.
Then according to him the dimensions of muscle are


ANSWER

$$ [MLT^{-2}] $$


SOLUTION
Let us represent the dimension of muscle as X and we are given $$X \times speed=power$$.

$$X \times speed = power = \dfrac{Work}{Time}$$$$=\dfrac{\left[ML^{2}T^{-2}\right]}{\left[T\right]}$$

Now, $$X=\dfrac{\left[ML^{2}T^{-3}\right]}{\left[LT^{-1}\right]}$$.

The dimension of muscle is $$\left[MLT^{-2}\right]$$.
