Question

What is the mass of an object that accelerates at 400 meter per second squared under the influence of 40 N?

Answer 1

Answer: I hope this helps

Explanation:

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.
