Question

A batter pops a ball straight up. a.) If the ball returns to the height from which it was hit 4.9 s later, what was its initial speed? 24.01 m/s b.) Does the ball reach its maximum height 2.45 s after it was hit, more than 2.45 s after it was hit, or less than 2.45 s after it was hit? Explain. c.) Find the maximum height of the ball, as measured from the point where it was hit. m d.) Sketch the shape of the position, velocity, and acceleration vs. time graphs of the ball during the entire flight. Mark any significant points you can. Take the +y direction to be upwards and ground level to be y=0. What is the shape of your y vs. t graph?: ---Select--- What is the shape of your vy vs. t graph?: ---Select--- What is the shape of your ay vs. t graph?: ---Select---
