A mother is holding her 4.5-kg baby in her arms while riding in a car moving at 22 m/s. The car is involved in a head-on collision and stops within 1.5 seconds. What is the magnitude of the force exerted by the baby on his mother's arms?

Question

Quizplus · Accepted Answer

The force exerted by the baby can be calculated using the formula F = ma, where m is the mass and a is the acceleration. The acceleration can be found using a = Δv/Δt = (0 - 22 m/s) / 1.5 s = -14.67 m/s². Thus, F = 4.5 kg * 14.67 m/s² = 66 N.
