Answer the following

Inelastic Collision Reset the simulation by clicking in the lower right. Set the initial velocity of mass 2 to zero and change the elasticity to 50%. The data should look like the picture on the front page. Now, kinetic energy is not conserved. Some of it is converted Elasticity 50% to internal energy. However, momentum should still be Inelastic Elastic conserved. Run the experiment again. The initial KE will be the same as before so you can just copy those from the previous table. 10-15 Initial momentum Final momentum Initial KE Final KE Mass 1 0.5 Mass2 0 Total 0.5 How much kinetic energy was lost during the collision? You can report this as the percent difference between the final and initial energy. Enter your result as a positive number. 16, Vinal-initiall x 100 = InitialStick Together Click the reset button, set the initial speed of mass 2 to zero, and set the elasticity to 13%, inelastic. In this type of collision, the objects stick together. "I'ou should be able to predict the speed of the pair after they collide using conseryation of momentum. m1 V1i= I:I1"I1 + I112} w 1?. Predict the final velocity ofthe two balls after they collide. W: Now run the experiment and see if your prediction was correct. Copy the initial KE from before and enter the nal momentum and HE for this collision. 15-13 Initial iiE Final iiE 24. How much kinetic energy was lost during the collision? Ifinol tutti-oil . H l = minor: Elastic Collision Change the initial velocity of ball 2 to zero. Your screen should look like this: 0.5 m Balls 2 7 0.00 S Normal G O Slow More Data Mass (kg) Position (m) Velocity (m/s) Momentum (kg m/s) X Vx Px 1 0.50 -1.70 1.00 0.50 2 1.50 0.00 0.00 0.00 Click the Play button, , and then pause after the collision. In the table below, enter the initial and final momentum for each ball. Include the negative sign if there is one. Also calculate the initial and final kinetic energy of each ball. With the elasticity set to 100%, kinetic energy should be conserved. 1-9 Initial momentum Final momentum Initial KE Final KE Mass 1 0.5 Mass2 0 Total 0.5 Add the momentum and energy of each ball to find the total before and after the collision. You should find that the total momentum and energy before and after the collision is the same
