You take the mass of the object 400 grams then what do you predict the force needed to move the object at a constant acceleration of 3/s2?

Answer:
Below
Explanation:
To find the force needed to move an object, you can use this formula :
force = (mass)(acceleration)
Plugging our values in...
force = (400g)(3 m/s^2)
= 1,200 Newtons
We can see how this works for the previous answers :
force = (100g)(3 m/s^2)
= 300 Newtons and so on....
Hope this helps! Best of luck <3
