An object starts falling falling from rest. It travels 2.78 m in 0.75s i) find the velocity of the object

ii) Find the average velocity of the object

iii) Why is the final velocity higher than the average velocity?

Show all steps so I can follow please and understand how you go to the answer.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
