A net force of 20 acting on a wooden block produces an acceleration of 4.0 m/s2 for the block.


What is the mass of the block?

Answer:
Simple physics.

Newton's second law of motion tells us that an object will accelerate in the direction of an applied force: F = m a

Rearrange the equation to find m: m = F/a

m = 20 N / (4.0 m/s^2) = 5.0 kg

The mass of the block is 5.0 kg
Force = Mass * Acceleration
Force = 20
Mass = ?
A = 4.0 m/s2

20 = Mass * 4.0 M/s2
20/4 = Mass
Mass = 5
Force divided by acceleration.

20 N / 4.0 m/s2 = 5 grams
