the image shows two opposite forces acting on a rolling cart, what can we say is true about the affect of the forces on the cart? a it cannot be determined without knowing which man is stronger. b it cannot be determined because one man is taller than the other. c the forces are unbalanced, and net force on the cart moves it to the left. d the forces are unbalanced, and net force on the cart moves it to the right.
Answer
Explanation:
Step1: Calculate net - force
The force acting to the right is $F_{right}=50N$ and the force acting to the left is $F_{left}=125N$. The net - force $F_{net}$ is calculated by subtracting the smaller force from the larger force. Since the forces are in opposite directions, $F_{net}=F_{left}-F_{right}$. $F_{net}=125 - 50=75N$ to the left.
Step2: Analyze the motion
When the net - force on an object is non - zero, the forces are unbalanced. Here, since $F_{net}=75N$ to the left, the cart will move to the left.
Answer:
C. The forces are unbalanced, and net force on the cart moves it to the left.
