D Question 5 2 pts A 145 g baseball with an initial velocity of 54 m/s collides with a 1 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 energy of the bat into the ball. This way, the final kinetic energy term is the ball only. The final kinetic energy term for the bat drops to O. Use the conservation of energy equation for kinetic energy: (velocity ) + Initial mass2 . (velocity2)2 = Final mass . (velocity)2 Initial mass = What is the final kinetic energy (Joules) of the baseball before the pitcher catches it? Give your numerical answer to the nearest whole number (singles digit). D Question 6 2 pts A projectile of mass 2 kg is launched horizontally from an initial height 1.4 m with an initial velocity 8.7 m/s. This velocity in the x direction is preserved when you ignore air resistance. The projectile still accelerates in the vertical y direction toward the ground, but this is exactly the energy lost from potential energy. Energy is conserved as long as you use the total mechanical energy equation. What is the total final kinetic energy (Joules) as the projectile just reaches the ground? Give your numerical answer to one decimal place precision. Assume g= 9.8 m/52
