When a certain force is applied to the 1-kg standard mass its acceleration is 5.0 m/s².When the same force is applied to another object its acceleration is one-fifth as much.The mass of the object is: A)0.2 kg B)0.5 kg C)1.0 kg D)5.0 kg E)10 kg

Question

Quizplus · Accepted Answer

The force applied to both objects is the same, so using Newton's second law (F = ma), the acceleration is inversely proportional to the mass. If the acceleration of the second object is one-fifth of the first (1 kg mass with 5 m/s^2 acceleration), its mass must be 5 times greater, making it 5.0 kg.
