Question

ling is sitting in a paddleboat that is floating on a lake. earths gravity is pulling down on the paddleboat with a force of 500 n. ling is pushing down on the paddleboat with a force of 550 n. the water in the lake is pushing up on the paddleboat with a force of 1,050 n. assume all other forces on the paddleboat are balanced. which statement describes the forces on the paddleboat? the forces are balanced, so there is no net force on the paddleboat. the forces are unbalanced, so there is a net force on the paddleboat.

Explanation:

Step1: Calculate total downward force

The total downward force is the sum of the gravitational - force on the paddleboat and Ling's pushing force. So, $F_{down}=500\ N + 550\ N=1050\ N$.

Step2: Compare with upward force

The upward force exerted by the water is $F_{up}=1050\ N$. Since $F_{down}=F_{up}$, the net force $F_{net}=F_{up}-F_{down}=1050\ N - 1050\ N = 0\ N$.

Answer:

The forces are balanced, so there is no net force on the paddleboat.
