Jonathan accelerates away from a stop sign. His eight-year-old daughter sits in the passenger seat. On whom does the back of the seat exert a greater force?

Solution: Step 1 of 2 Newton’s second law of motion says that the force exerted on an object is directly proportional to the mass of the object and the acceleration given to the object. Mathematically, force is equal to the mass times the acceleration is given which can be written as follows, F= ma Here, F is the force exerted on the body, m is the mass of the object and a is the acceleration.
