Newton’s Laws of motion I. First Law 1. You are in a car as it turns a corner. You feel yourself pressed against the car door. Use the ideas of force and inertia to explain this experience. II. Second Law 2. Find the force acting on a 1.0-kg box that is resting on a flat surface given the vector diagram shown at right. You need to determine the magnitude of the up and downward force. Then find the acceleration of the box as a result of this net force. 3. A 50.0-kg crate sits on the ground. You pull upward on it with a force of 6.0 x 102 N. a. What is the weight of the crate? (Weight is the mg of the box) b. Draw a free-body diagram showing the forces acting on the crate. c. What is the total force acting on the crate? (add all the x and y forces) What is its resulting acceleration? (use F=ma) III. Third Law 4. A 7-kg bowling ball hits a 0.6-kg bowling pin. The pin accelerated at 40 m/s2. a. Calculate the force exerted by the ball on the pin. What is the magnitude of the force on the bowling ball? (remember forces are equal and opposite) b. What is the ball’s acceleration? (F=ma)
