DMENTUM PLAY STOP 19 A 50 kg ball rolls down the street at \( 5 \mathrm{~m} / \mathrm{s} \). Calculate the momentum of the ball. (A) \( 250 \mathrm{~kg} \hbar \mathrm{~m} / \mathrm{s} \) (B) \( 500 \mathrm{~kg} \hbar \mathrm{~m} / \mathrm{s} \) (C) \( 100 \mathrm{~kg}^{\star} \mathrm{m} / \mathrm{s} \) (D) \( 55 \mathrm{~kg} \pi \mathrm{~m} / \mathrm{s} \)

To calculate the momentum of the ball, we can use the formula for momentum \( p \): \[ p = m \cdot v \] where: - \( p \) is the momentum, - \( m \) is the mass of the object (in kg), - \( v \) is the velocity of the object (in m/s). Given: - Mass \( m = 50 \, \text{kg} \) - Velocity \( v = 5 \, \text{m/s} \) Now, we can substitute the values into the formula: \[ p = 50 \, \text{kg} \cdot 5 \, \text{m/s} \] Calculating this gives: \[ p = 250 \, \text{kg} \cdot \text{m/s} \] Now, let's compare this result with the provided options: (A) \( 250 \, \text{kg} \cdot \text{m/s} \) (B) \( 500 \, \text{kg} \cdot \text{m/s} \) (C) \( 100 \, \text{kg} \cdot \text{m/s} \) (D) \( 55 \, \text{kg} \cdot \text{m/s} \) The correct answer is: **(A) \( 250 \, \text{kg} \cdot \text{m/s} \)**.
