Mass is indirectly proportional to acceleration, so, lighter the object greater would be it's acceleration...
A) 0.10 kg is lightest among them, so it's your answer
Answer : A) 0.10kg beach ball
Explanation : Given a force of 10.0 Newtons, which mass will have the greatest acceleration?
0.10 kg beach ball
F=ma
Rearranging for acceleration gives
a=F/m
For the beach ball
a=(10.0 Newtons)/(0.10 kg)
a=100 m/s2
For the brick
a=(10.0 Newtons)/(2.0 kg)= 5 m/s2
For the steel ball
a=(10.0 Newtons)/(5.0 kg)= 2 m/s2
For the bag of feathers
a=(10.0 Newtons)/(10.0 kg)= 1 m/s2
