Question

What is the mass of an object that has a 250 N force moving at an acceleration of 10 m/s2 ?

Answer 1

Answer: 25 kg

Identify the given information.
f = 250 N
a = 10 m/s^2 
 
Choose which formula you should use. In this case, you are finding the mass.
The formula for force is f = ma, so, using this, it is easy to find the mass.

f = ma         Divide by a for both sides
m = f/a        Formula for mass!

The formula for mass is m = f/a, where f is force and a is acceleration.

Substitute.
m = (250 N)/(10 m/s^2)
m = 25 kg
