Question

How much force is required to accelerate an 8kg mass at 5m/s^2

Answer 1

Force = mass times acceleration.

We do not know the force, but we know the mass and acceleration.

f = 8kg * 5m/s^2

8*5 = 45

f = 45 kg * m/s^2

f = 45 newtons

Final answer: The force required is 45 N.

Answer 2

45 newtons is the right answer
f 45 kg 
f 45 newtons
