Dimensional formula for impulse

The dimensional formula for impulse is

\( [\text{MLT}^{-1}] \)

\( [\text{M}^{-1}\text{LT}] \)

\( [\text{M}^{-1}\text{LT}^{-1}] \)

\( [\text{ML}^{-1}\text{T}^{-1}] \)

Impulse is defined as Force multiplied by time, \( I = F \cdot t \). Its dimensions are \( [\text{MLT}^{-2}][\text{T}] = [\text{MLT}^{-1}] \).
