True / False:
If a 40 kg person is accelerating at 10 m/s^2,then the magnitude of the force acting on him or her is 400 N.
1.How much force is needed to make a 60 kg object accelerate at a rate or 2.0 m/s ^2?
2.What is the acceleration of a 30 kg objedct when 180 n of force is aplied to it?
3.Which of the following equation shows how you would solve for mass if you know the force acting on an object and the accleration of an object?
a~m=f/a

thax emma your the best
You can apply Newton's Second Law, which is essentially Force = Mass x Acceleration.
For the first question, have a mass of 40kg and an acceleration of 10m/s^2, which means that the Force will be 400N.
1. Calculate force by multiplying mass by acceleration, so 60kg x 2.0m/s^2 which will result in a force of 120N.
2. You can rearrange the variables in the equation F=m*a as a=F/m. Take the force applied and divide it by the mass, so 180N / 30kg which is 6m/s^2.
3. If you know the force and acceleration of the object, you can rearrange the equation F=ma to m=F/a.
