Compute all parts of given question:
Question: In t-ball, young players use a bat to hit a stationary ball off a stand. The 140 g ball has about the same mass as a baseball, but it is larger and softer. In one hit, the ball leaves the bat at 12m/s after being in contact with the bat for 2.0ms. Assume constant acceleration during the hit.
Part I: What is the acceleration of the ball?
Part II: What is the net force on the ball during the hit?
I need help to solve the above question and express your answer to two significant figures and include the appropriate units.
