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) zero the inverse of the mass the mass the velocity

Explanation:

To solve this, we use Newton's second law, \( F = ma \), where \( F \) is force, \( m \) is mass, and \( a \) is acceleration. When graphing force (\( y \)-axis) vs. acceleration (\( x \)-axis), the equation becomes \( F = ma + b \), where \( b \) is the \( y \)-intercept. Since the motorboats have the same mass and there's no other force (like friction assumed to be zero for this idealized experiment), when acceleration \( a = 0 \), force \( F = 0 \). So the \( y \)-intercept (when \( a = 0 \)) is zero.

Answer:

A. zero
