Question

1. An object accelerates 5.0 m/s when a force of 20.0 newtons is applied to it.

What is the mass of the object?

2. An object accelerates 2.0 m/s when a force of 12.0 newtons is applied to it.
What is the mass of the object?

3.An object accelerates 16.3 m/s when a force of 4.6 newtons is applied to it.
What is the mass of the object?

Answer 1

1. mass = 4

2. mass = 6

3. mass = 0.28

Step-by-step explanation:

All these questions require the equation:

F=ma

Where F is force, m is mass and a is accleration. If we do some algebra, we can modify this equation to find mass by dividing both sides by a.

`F=ma --> (F)/(a) =(ma)/(a) --> (F)/(a) = m`

The a on the left side cancels out and leaves us with
`(F)/(a)=m`. Now we can plug in the numbers given to find the mass.

1.
`(F)/(a) =m-->(20.0)/(5.0)=m-->m=4`

2.
`(F)/(a) =m -->(12.0)/(2.0) =m -->m=6`

3.
`(F)/(a)=m--> (4.6)/(16.3)=m--> m=0.28`

So the answers are m=4, m=6, and m=0.28.
