The acceleration of an object varies directly with the force acting on it. If a force of 70 newtons causes an acceleration of 6.5 m/s2, what force will cause ann acceleration of 8m/s2? round your answer the hundredths place

Respuesta :

By using the formula;

Acceleration = k x force

Now we first solve for the k using force = 7o newtons and acceleration = 6.5m/s²

A = k x f

6.5 = k x 70

K = 6.5/70 = 0.093

Now, we find the force that causes an acceleration of 8 m/s²

A = k x f

8 = 0.093 x f

F = 8 / 0.093

F = 86.02 newton
