Kyela and her brother are roller skating. Kyela as a mass of 60 kg and her brother has a mass of 30 kg.

When Kyela pushes off her brother, how do their accelerations compare?

Kyela accelerates faster than her brother.

Her brother accelerates faster than Kyela

They both have the same acceleration

Neither will accelerate, because they are traveling at constant velocity
