![]() ![]() For vertical projectile motion, alpha is 90 degrees. Immediately after the ball is hit, the third baseman turns and runs at a. (Figure 1) A batter hits a softball over a third baseman's head with speed vo and at an angle from the horizontal. Science Across the Curriculum Project Capital University Projectile Motion. To be able to calculate the velocity and the angle of trajectory of an object undergoing projectile motion. That model is then used to calculate the trajectories for the remaining data. Now to find the total time in the air, we use the definition of acceleration to find the time it takes the ball to get to the top of its arc, the acceleration in this case being $g = 9.8 m/s^2.$ We can rearrange that definition to find the elapsed time. Why do the balls pass the batter at different heights SOLUTION: The faster ball is in the air a shorter time, and thus gains a smaller vertical velocity. Students can use this calculator to check homework solutions. Mechanical Engineering questions and answers. ![]()
