Question

When the car is moving the unbalanced force acting on the car is 150 N.

A) State the equation which relates unbalanced force, mass and acceleration?​

Answer 1

F = m a, a = 0.3 m / s²

this acceleration points in the direction of the unbalanced force

Step-by-step explanation:

In this problem we must use Newton's second law. Let's fix a reference system with the x axis parallel to the surface and the y axis perpendicular

Y axis y

N-W = 0

N = W = mg

X axis

∑ F = m a

F = m a

we substitute

150 = m a

To find an acceleration value, the mass of the car must be known, if the mass is m = 500 kg

a = 150/500

a = 0.3 m / s²

this acceleration points in the direction of the unbalanced force
