Answer:
x=72°
Step-by-step explanation:
We know angles around a point equals 360°
Therefore,
(2x-61)°+(x-11)°+3x°=360°
2x-61+x-11+3x=360°
Collect like terms,
2x+x+3x-61-11=360°
6x-72°=360⁰
Evaluate;
6x=360°+72°
6x=432°
Divide both sides by 6
x=72°

Answer:
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
