a) Which ball will take longer to hit the ground? same time (Same Initia) hoight, Speed acceloration
b) What is the difference in time for the two balls to hit the ground? no differena
c) If Ball B were released 1 second before ball A, at what height will ball A catch up to ball B? 4t the grane
2) [Vertical] A green ball (m 2 kg) is dropped from a height of 8.00 m above the ground. At the
moment it is dropped, a red ball (m = 3 kg) is shot straight up into the air from the ground (but not so
that the two balls collide). How fast does the red ball need to be shot in order for it to land on the
ground at the same time the green ball hits the ground?
