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

$[MLT^{-2}]$

##### 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 $\left[MLT^{-2}\right]$.
