Question

A force of 15 newtons is applied to both Object A with a mass of 25 kilograms and Object B with a mass of 50 kilograms. What is true about the acceleration of Object A and Object B?

Answer 1

To analyze the differences in acceleration of the two objects, a necessary formula/relation to remember here is force = mass * acceleration. Given the different data in the problem, we can solve for the acceleration of each object. This is shown below:

Force = 15 N
M1 = 25 kg
M2 = 50 kg
a1 = ?
a2 = ?

For object 1:

15 N = 25 kg * a
a = 0.6

For object 2:

15 N = 50 * a
a = 0.3 

Therefore, the acceleration of Object B is half that of Object A.
