What force is generated by a 10,000 kg mass accelerating at 4.3 m/s squared

43,000 N

Explanation:

Force = mass * acceleration

F = ma

F = (10,000 kg) (4.3 m/s²)

F = 43,000 N

No force is 'generated'.

What's generated is the acceleration.

If you want a 10,000 kg mass to accelerate at 4.3 m/s^2, then you need to find some way to push it with 43,000 Newtons of force ... almost 9,700 pounds!

The force causes the acceleration.
