The momentum of the ball is
.
Explicación
## Step 1: First, we need to understand the problem. We are given the mass of the ball (29 kg), its initial velocity (2.2 m/s), and the time it takes to stop (4.4 seconds). We are asked to find the momentum of the ball.## Step 2: Momentum is defined as the product of an object's mass and its velocity. In this case, since the ball comes to a stop, its final velocity is 0 m/s. Therefore, the momentum of the ball is simply the product of its mass and its initial velocity.### The formula for momentum is: ###
## Step 3: Substitute the given values into the formula. The mass of the ball (m) is 29 kg and the initial velocity (v) is 2.2 m/s.## Step 4: Calculate the momentum by multiplying the mass and the velocity.
