lifting a 70 kg sack vertically 1 meter
ent
pushing a 35 kg sack 2 meters
lifting a 35 kg sack vertically 2 meters
lifting a 35 kg sack vertically 1 meter
© pushing a 70 kg sack 1 meter

are their multiple choices ?

explanation:

close lines strong magnet less close weaker

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.
