A0,560 kg model rocket produces 53.0 newton's of upward thrust as it shoots upward off the launch pad. with what acceleration meters per second-squared does the rocket launch

i think the answer is a, hope this is right, that would be my best guess.

object 2 because all the other ones are wrong

the answer would be 32*f

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
