Question

kylie and bobby are trying to open their garage door because the remote is broken. kylie is pulling up on the garage door with a force of 320 n. bobby is pulling up on the garage door with a force of 300 n. earths gravity is pulling down on the garage door with a force of 600 n. assume all other forces on the garage door are balanced. which statement describes the forces on the garage door? the forces are balanced, so there is no net force on the garage door. the forces are unbalanced, so there is a net force on the garage door.

Explanation:

Step1: Calculate upward forces

The upward - acting forces are Kylie's force and Bobby's force. The sum of the upward forces $F_{up}=320 + 300=620$ N.

Step2: Determine downward force

The downward - acting force is the force of gravity, $F_{down}=600$ N.

Step3: Calculate net force

The net force $F_{net}=F_{up}-F_{down}=620 - 600 = 20$ N. Since $F_{net}
eq0$, the forces are unbalanced.

Answer:

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