Three balls of different masses are thrown straight upward with initial speeds as indicated. a. From fastest to slowest, rank the speeds of the balls 1 s after being thrown. b. From greatest to least, rank the accelerations of the balls 1 s after being thrown. (Or are the accelerations the same?)
Solution: The above figure mention three different masses : A = 1.0 kg, 10 m/s B = 1.5 kg, 15 m/s C = 0.8 kg, 0.8 m/s With the initial speed as indicated as, (a) From fastest to slowest, rank the speeds of the balls 1 s after being thrown. B ( 0 m/s ), C (5 m/s), and A (10 m/s). (b) From greatest to least, rank the accelerations of the balls 1 s after being thrown. (Or are the accelerations the same) Yes, All the acceleration are same, because the acceleration due to gravity.
