In the imаge belоw, а bаll is thrоwn vertically upwards frоm the ground to a friend located at a window. You can neglect any air resistance. Use kinematics to do the following: (a) Calculate how fast the ball was thrown upwards if your friend catches it just as the ball stops moving. Instead, the ball is thrown upwards with a speed of 30 m/s. (b) If the friend does not catch the ball, calculate the time the ball is in the air from when it was first thrown until the friend sees the ball on the way down.
