Ablue ball is thrown upward with an initial speed of 21.6m/s, from a height of 0.8 meters above the grpund. 2.6 seconds after the blue ball is thtown, a red ball is thrown down with an initial spees of 8.3m/s from a height of 26.1 meters above the ground. the force of the gravity due to the earth results in the balls each having a constant downward acceleration of 9.8m/s
1.what is the max. height the blue ball reaches?
2. what is the height of the red ball 3.38 seconds after the ball is thrown
3. how long after the blue ball isbthrown are the two balls in the air at the same height?

Amerry-go-round of radius r, shown in the figure, is rotating at constant angular speed. the friction in its bearings is so small that it can be ignored. a sandbag of mass m is dropped onto the merry-go-round, at a position designated by r. the sandbag does not slip or roll upon contact with the merry-go-round. how would you rank the following different combinations of m and r on the basis of the angular speed of the merry-go-round after the sandbag "sticks" to the merry-go-round from largest to smallest. a) m = 10kg, r = 0.25r b) m = 20kg, r = 0.25r c) m = 10kg, r = 0.50r d) m = 10kg, r = 1.0r e) m = 15kg, r = 0.75r f) m = 40kg, r = 0.25r
