How much force is needed to accelerate an object of mass 90 kg at a rate of 1.2 m/s? ?
0.013 n
75 n
108 n
1080n

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.
