I need some practice with these problems in Physics. I'm taking some extra work so I can study so I'm using a few practice problems.

Answer the following questions based on the scenario: A bat striking a 0. 125 kg baseball is in contact with the ball for a time of 0.03 seconds. The ball travels in a straight line as it approaches and then leaves the bat. If the ball arrives at the bat with a leftward speed of 4.5 m/s and leaves with a speed of 6.5 m/s in the opposite direction, what is the magnitude of the average force acting on the ball? (Use the Impulse- Momentum Theorem for this question) Which of the following is an INCORRECT adaptation of the impulse- 2 points momentum theorem * A. FAt = mvf - mvi B. FAt = m(vf- vi) C. FAt = mvi- mvf D. FAt = pf - Pi O A O B O C O D The correct set of givens are... 2 points * A. B. m = 0.125 kg m = 0.125 kg Vinitial = 4.5 m/s Vinitial = 6.5 m/s Vfinal = 6.5 m/s Vfinal = -4.5 m/s At = 0.03 s At = 0.03 s F =? F =? C. D. m = 0.125 kg m = 0.125 kg Vinitial = -4.5 m/s Vinitial = 6.5 m/s Vfinal = 6.5 m/s Vfinal = 4.5 m/s At = 0.03 s At = 0.03 s F =? F =?The correct values for the initial and final momentum of the baseball are... * O pi = -0.56 kgm/s pf = 0.81 kgm/s pi = 0.81 kgm/s pf = 0.56 kgm/s pi = 0.81 kgm/s pf = 0.-0.56 kgm/s pi = 0.56 kgm/s pf = 0.81 kgm/s T or F: If an object changes direction during a collision, there is an subtractive effect on its change in momentum.* True False What is the average force that acts on the baseball from the bat? * O 8.33 N O 18.75 N O 27.08 N O 45.83 N O 458 NStep by Step Solution
