2. The vertical component of the velocity of a bouncing ball as a function of time is shown in the graph below. - The positive y direction is vertically up. - The ball deforms slightly while it is in contact with the ground.mingle in vy (m/s) A 9.0 6.0 3.0 1/0 bor 0 0 5 1/5 20 5 3/0 40 t (s ) - 3.0 - 6.0 - 8:93209 WOVTO1 - 9.0 a) Identify two instances of time at which the ball is at its maximum height and write them below. Do not include "t=0s" in your answer. HINT: Velocity is a vector - what does a positive velocity mean about the direction the ball is moving? What does a negative velocity mean? b) Calculate the acceleration of the ball WHILE IT IS IN THE AIR. Remember, acceleration is a vector and it has units. SHOW ALL WORK here : Agiant c) Calculate the acceleration of the ball WHILE IT IS IN CONTACT WITH THE FLOOR. Remember, acceleration is a vector and it has units. SHOW ALL WORK here : d) Using the area under the Velocity-Time graph, calculate the maximum height above the floor that the ball reaches. Be sure to only utilize the portion of the Velocity-Time graph that corresponds to the ball in free fall. SHOW ALL WORK here
