A constant force applied to object A causes it to accelerate at 6m/s2 .The same force applied to object B causes an acceleration of 3m/s2 . Applied to object C, it causes an acceleration of 7m/s2 .

A) Which object has the largest mass?

B) Which object has the smallest mass?

C) What is the ratio of mass A to mass B?

Explanation:

Force, F = M * a

Where,

M = mass

a = acceleration

Object A

F = Ma * 6

= 6Ma

Object B

F = Mb * 3

= 3Mb

Object C

F = Mc * 7

= 7Mc

A.

Calculating their masses,

Object A

F/6 = Ma

Object B

F/3 = Mb

Object C

F/7 = Mc

Object B of mass, F/3 has the largest mass.

B.

Object C of mass, F/7 has the smallest mass.

C.

Mass of Object A : Mass of Object B

= F/6 : F/3

= 1 : 2
