Final answer:
The mass of a ball with momentum of 1.0 kilogram meter per second and a velocity of 2.0 meters per second is 0.5 kilograms.
Step-by-step explanation:
To calculate the mass of the ball, given the momentum and velocity, we use the formula for momentum (p = m × v), where p represents momentum, m is mass, and v is velocity. We can rearrange this formula to solve for mass (m = p / v).
Substituting the known values into the equation, we have m = 1.0 kg·m/s / 2.0 m/s, which simplifies to m = 0.5 kg. Therefore, the mass of the ball is 0.5 kilograms.
