Verified step by step guidance1
Recall the definition of momentum, which is given by the formula: \(\text{momentum} = \text{mass} \times \text{velocity}\).
Identify the known quantities from the problem: mass \(m = 2\,\text{kg}\) and momentum \(p = 16\,\text{kg} \cdot \text{m/s}\).
Rearrange the momentum formula to solve for velocity: \(v = \frac{p}{m}\).
Substitute the known values into the equation: \(v = \frac{16}{2}\).
Calculate the velocity by performing the division to find the speed of the cart.
