\fInstructions: Click the link to PhET Simulation. When you reach the website, press play and select Intro. Set the elasticity to 25% and expand the momentum diagram. Before running the simulation, also check the slow option under the simulation. Press playr and let the simulation run. Questions: Choose which option best describes the momentum and mechanical energy: A. Both Momentum and Mechanical energy are conserved B. Momentum is conserved, but Mechanical energy is not C. Momentum is not conserved, but Mechanical energy is D. Neither are conserved Does the momentum decrease? Yes or No Determine the initial momentum p;, final momentum pf, and change in momentum Ap of a 1250-kg car initially backing up at 6.00 m/s, then moving forward at 15.0 m/s. Define forward as the positive direction. Pi = kg.m/s Pf = kg.m/s Ap = kg.m/s. A baseball of mass 0.145 kg is thrown at a speed of 35.0 m/s. The batter strikes the ball with a force of 25,000 N. The bat and ball are in contact for 0.500 ms. Assuming that the force is exactly opposite to the original direction of the ball, determine the nal speed of of the ball. Ur = m/s 1' TOOLS x10Fr During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 146 g baseball crashing through the pane of a second-oor window in a nearby building. The ball strikes the glass at 10.1 rn/s, shatters the glass as it passes through1 and leaves the window at 8.17 mfs with no change of direction. Calculate the magnitude of the impulse J that the glass If the baseball is in contact with the glass for a time At of 10.5 ms, what is the magnitude of the average force Favem e _ g F average N of the glass on the ball
