Question

lauren and vivian are trying to push their car out of the mud. lauren is pushing the car forward with a force of 600 n. vivian is pushing the car forward with a force of 550 n. the mud is pushing the car backward with a force of 1,100 n. assume all other forces on the car are balanced. which statement describes the forces on the car? the forces are balanced, so there is no net force on the car. the forces are unbalanced, so there is a net force on the car.

Explanation:

Step1: Calculate the net force

The formula for net force \(F_{net}\) is \(F_{net}=F_{forward}-F_{backward}\).
The forward forces are \(F_{Lauren} = 600\space N\) and \(F_{Vivian}=550\space N\), so the total forward force \(F_{forward}=600 + 550=1150\space N\).
The backward force \(F_{backward}=1100\space N\).
Then \(F_{net}=1150 - 1100\).

Step2: Analyze the result

\(F_{net}=50\space N\). Since \(F_{net}
eq0\), the forces are unbalanced, so there is a net force on the car.

Answer:

The forces are unbalanced, so there is a net force on the car.
