Question

Three woman are pushing strollers with an equal amount of force. One stroller has a mass of 20 kg, another has a mass of 12 kg, and the last has a mass of 15 kg. Which stroller has the greatest change in speed?

Answer 1

Assuming each force applied is the same, the greatest acceleration (change in speed) must have the smallest mass (12kg). It’s helpful to remember the concept of inertia—the more mass you have, the more difficult it is to accelerate.
