Final answer:
The momentum of a 4 kg ball thrown at 2 m/s is 8 kg·m/s. Momentum is calculated with the formula p = m × v, applying this to a practice problem, a 5 kg bowling ball with velocity 10 m/s would have a momentum of 50 kg·m/s.
Step-by-step explanation:
Calculating Momentum
To calculate the momentum of an object, you can use the equation p = m × v, where p is momentum, m is mass in kilograms, and v is velocity in meters per second. Therefore, to find the momentum of a 4 kg ball thrown at 2 m/s, substitute the given values into the equation: p = 4 kg × 2 m/s, which equals 8 kg·m/s.
