Question

Several motorboats with the same mass are used in an experiment. The forces of the different motors versus their accelerations are graphed. What is the y-intercept of this graph? (1 point) Responses the mass the mass the velocity the velocity zero zero the inverse of the mass

Answer 1

The y-intercept of the graph plotting the forces of the different motors against their accelerations represents the value of the force when the acceleration is zero. According to Newton's second law (\( F = ma \)), if the acceleration \( a \) is zero, then the force \( F \) must also be zero if we are only considering the net force acting on the motorboats.

Therefore, the correct response is **zero**.
