Final answer:
The mass of the tennis ball is 58.89 grams.
Step-by-step explanation:
To find the mass of the tennis ball, we can use the equation for momentum, which is given by momentum = mass x velocity. Rearranging the equation, we can solve for mass: mass = momentum / velocity. Plugging in the given values, we get mass = 1.06 kg • m/s / 18 m/s.
To convert the mass from kilograms to grams, we multiply by 1000 since there are 1000 grams in a kilogram. Therefore, the mass of the tennis ball is 1.06 kg • m/s / 18 m/s x 1000 g/kg = 58.89 grams.
