Answer:
I think the answer is 180 degree angle
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
The solution to the system of equation is (-4 , 2) , Option A is the right answer.
<h3>What are System Of equation ?</h3>
A set of equation whose factors are common are called system of equations.
It is given in the question
3x +5y = -2
3x +7y = 2
On solving this we get
-2y = -4
y = 2
On substitution in any equation
x = -4
Therefore solution to the system of equation is (-4 , 2) , Option A is the right answer.
