A blue ball is thrown upward with an initial speed of 22.2 m/s,from a height of 0.5 meters above the ground. 2.7 seconds after theblue ball is thrown, a red ball is thrown down with an initialspeed of 10.7 m/s from a height of 26.9 meters above the ground.The force of gravity due to the earth results in the balls eachhaving a constant downward acceleration of 9.81 m/s2
a. What is the height of the red ball 3.51 secondsafter the blue ball is thrown?
b. How long after the blue ball is thrown are the two balls inthe air at the same height?
c. Which plot correctly shows the velocity of the two balls as afunction of time?
d. Which statement is true about the blue ball after it hasreached its maximum height and is falling back down?
The acceleration is positive and it is speeding up
The acceleration is negative and it is speeding up
The acceleration is positive and it is slowing down
The acceleration is negative and it is slowing down
