D Question 2 2 pts A 145 g baseball with an initial velocity of 124 m/s collides with a 1.5 kg baseball bat moving at 19 m/s in the opposite direction. The batter hits the ball at high speed directly back to the pitcher, and the pitcher makes a miraculous catch. Assume the batter stops the swing during the collision, transferring all of the momentum of the bat into the ball. This way, the final momentum term is the ball only. The final term for the bat drops to O. The x-axis is positive for the ball moving towards the pitcher and away from the batter. Use the conservation of momentum equation: Initial mass . velocity, + Initial massz . velocityz = Final mass . velocity What is the final velocity of the baseball before the pitcher catches it? Give your numerical answer to the nearest whole number (singles digit). D Question 3 2 pts During a snowball fight, two students throw snowballs at each other at the same time. Imagine that both snowballs have the same mass and are thrown with the same initial speed. The snowballs collide in midair and stick together, then fall down. Immediately after the collision, what is the final momentum of the combined mass before falling down (don't allow time for gravity to act)? (Insert the number only without units.) 0 D Question 4 1 pts Conservation equations are powerful equations, because of how versatile and flexible they are to different physical situations. Conservation of mass is a simple one that can even be applied to fluids with care. The conservation of momentum also applies to any closed system, such as collisions. We've examined the nuances of energy conservation in our labs with total mechanical energy. Does kinetic energy remain conserved in all collisions too? True False
