Question

Using newton's second law of motion, if the force on an object is 20n, and its mass is 5g, what is the acceleration? Can someone explain to me in a simple way how to do this? I have tried but the formulas I see are confusing. Thank you :)

Answer 1

Do 20 divided by 5 and you'll get 4! All you have to do is take the net force (20n) and divide it by the mass (5g) and you'll have the answer! :)

Answer 2

Answer: The acceleration of the object will be 4000
`m/s^2`

Step-by-step explanation:

According to second law of motion:

`Force(F)=mass(m)* acceleration(a)`

Unit of the force:
`N=kg* m/s^2`

According to question we have :

Force = 20 N

Mass of the object = 5 g = 0.005 kg (1 kg =1000 g)

Acceleration = ?

By using the second law of motion = F= ma

`20 N= 0.005 kg* a`

`a=(Force)/(mass)=(20 N)/(0.005 kg)=4000 m/s^2`

The acceleration of the object will be 4000
`m/s^2`
