Ответ:
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 kilograma is the acceleration that the object accelerates with it in meter per square secondA 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
