Verified step by step guidance1
Identify the given quantities: mass \(m = 4\ \text{kg}\) and momentum \(p = 12\ \text{kg}\cdot\text{m/s}\).
Recall the relationship between momentum, mass, and velocity: \(p = m \times v\), where \(v\) is the speed of the ball.
Rearrange the formula to solve for speed: \(v = \frac{p}{m}\).
Substitute the known values into the equation: \(v = \frac{12}{4}\).
Calculate the quotient to find the speed of the ball (do this calculation yourself to get the final answer).
