Question

1. A 3,000-N force gives an object an acceleration of 15 m/s². The mass of the object is

2.4. The relationship among force, mass, and acceleration is stated in

Answer 1

f=m * dv/dt + v * dm/dt   (Newton's second law of motion)

In most case mass does not change so

f=ma  (force = mass * acceleration)

3000 = m * 15

m = 200kg
