Using Newtons second law of motion if the force on an object is 20N, and its mass is 5g, what is it's acceleration?
A=F/M
A=20N/5g
now I'm not sure what to do. Can someone please help?
Read all about it!
You need mass in kg
acceleration in m/s^2 is force in newtons, divided by mass in kilograms.
Would it be
20N=20kgm?s^2/5g=4m/s^2
a = F/m =20/0.005 = 4000 m/s^2

To find the acceleration using Newton's second law of motion, you would first need to convert the mass from grams to kilograms. Since 1 kg = 1000 g, divide the mass by 1000 to convert it to kilograms:
Mass = 5 g ÷ 1000 = 0.005 kg
Now, you can plug the values into the equation A = F/M:
Acceleration (A) = Force (F) / Mass (M) = 20 N / 0.005 kg
Divide the force by the mass to get the acceleration:
A = 20 N / 0.005 kg
A = 4000 kg·m/s²
Therefore, the acceleration of the object is 4000 meters per second squared or 4000 m/s².
