Question

object | mass (kg)
cannon | 150
fishing trap | 70
log | 30
row boat | 90
the ship has the same acceleration as it begins each trip. order the loads to show the size of the force on the ship each time it starts to sail.
larger force
20 cannons
2 fishing traps
10 logs
5 row boats

Explanation:

Step1: Calculate mass for 20 cannons

Each cannon is 150 kg, so total mass is \(20\times150 = 3000\) kg.

Step2: Calculate mass for 2 fishing traps

Each fishing trap is 70 kg, so total mass is \(2\times70 = 140\) kg.

Step3: Calculate mass for 10 logs

Each log is 30 kg, so total mass is \(10\times30 = 300\) kg.

Step4: Calculate mass for 5 row boats

Each row boat is 90 kg, so total mass is \(5\times90 = 450\) kg.

Step5: Order by mass (force is proportional to mass as acceleration is constant, \(F = ma\))

From largest to smallest mass (and thus force): 20 cannons (3000 kg), 5 row boats (450 kg), 10 logs (300 kg), 2 fishing traps (140 kg).

Answer:

From larger force to smaller force: 20 cannons, 5 row boats, 10 logs, 2 fishing traps
