From the graph, we can conclude that, all five motorboats have the same mass, which can be calculated from the graph.

From Newton's law, we have that; F = ma where F is the force on the body, m is the mass and a is the acceleration.

If we plot the force against the acceleration of the motorboats, the result is a sloped line with a y-intercept of zero.

We can obtain the mass as the motorboats from the slope of the line using any two points on the graph.

Therefore, we can obtain the mass of all five motorboats from the graph.
