2. If a 150kg cannonball begins accelerating at 40m/s/s, what net force does it have?

The net force that the object has is 6000 newtons

Step-by-step explanation:

The net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object

F = m a, where

m is the mass of the object in kilogram a is the acceleration that the object accelerates with it in meter per square second

A cannonball begins accelerating at 40 m/s²

∴ The acceleration is 40 meters per square second

∴ a = 40 m/s²

∵ The mass of the cannonball is 150 kilograms

∴ m = 150 kg

- Substitute a and m in the rule of the force

∵ F = m a

∴ F = 150 (40)

∴ F = 6000 newtons

The net force that the object has is 6000 newtons
