A body is moving with an acceleration of 60 m/s^2(square).If the force applied to the body is 4200N. Calculate its mass.

Hello, for this use the 2nd law of Newton:

F = ma

Replacing:

4200 N = m * 60 m/s^2

Resolving:

4200 N / 60 m/s^2 = m

70 kg = m

The mass is 70 kg

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
