2 15 39 52 95 36 86 Name: Learning Objectives: 1. Understanding the relationship between force, distance and changes in kinetic energy. 2. Understanding the relationship between force, time and changes in momentum. 3. Understanding the relationship between force and work. Changes in Energy and Momentum 4. Understanding the relationship between force and impulse. Apparatus: Aluminum track, track legs, smart cart with cart fan, two cart stops, and four 100g masses. Part A: Predictions cart stop A Flow smart cart with fan cart stop Before watching the video using the equipment as drawn above, consider the situation shown above (call this case) #1). The cart (mass m) starts from rest a distance d from the cart stop. The fan is used since it provides a constant force as the cart moves to the right and collides with the cart stop. Just before the collision the cart is moving with velocity v 8 07 03 51 28 55 92 14 96 164 539 825 202 225 2439 2662 2895 3136 3386 1. Identify the forces on the cart when the fan is running. Then draw the free body diagram for the cart. Indicate the direction of the net force and acceleration next to the free body diagram. List of Forces Free-body diagram 2.
