Newton's Second Law of Motion - Worksheet 1. A little boy pushes a wagon with his dog in it. The mass of the dog and wagon together is 45 kg. The wagon accelerates at 0.85 m/s². What force is the boy pulling with? 2. A 1650 kg car accelerates at a rate of 4.0 m/s². How much force is the car's engine producing? 3. A 68 kg runner exerts a force of 59 N. What is the acceleration of the runner? 4. A crate is dragged across an ice covered lake. The box accelerates at 0.08 m/s² and is pulled by a 47 N force. What is the mass of the box? 5. 3 women push a stalled car. Each woman pushes with a 425 N force. What is the mass of the car if the car accelerates at 0.85 m/s2? 6. A tennis ball, 0.314 kg, is accelerated at a rate of 164 m/s² when hit by a professional tennis player. What force does the player's tennis racket exert on the ball? 7. In an airplane crash a woman is holding an 8.18 kg baby. In the crash the woman experiences a horizontal de-acceleration of 88.2 m/s². How many g's is this de-acceleration? How much force must the woman exert to hold the baby in place?
