A speedboat and its captain with a mass of 734 kg have an acceleration of 0.723 m/s^2. For it to not accelerate more than 0.530 /s’ how much weight would they have to add to the bottom of the boat?

Answer 1

Hey Mezmre T.,

F = ma .

So if you increase the mass to a new amount, but hold the force the same (you don't change the engine!) the acceleration goes down inversely. You can do the ratios, I think? Remember that the new mass you calculate is the total, so you must subtract the original mass to obtain the added mass.
