An object experiences a net force of 20 N and has an acceleration of 4 m/s². The object's mass must be A) 20 kg B) 5 kg C) 80 kg D) 2 kg

Question

Quizplus · Accepted Answer

The object's mass can be calculated using Newton's second law of motion, F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration. Rearranging the formula to solve for mass gives m = F/a. Substituting the given values (F = 20 N, a = 4 m/s^2) gives m = 20 N / 4 m/s^2 = 5 kg.
