Sagot :
The system with the greatest acceleration, according to Newton's second law, is a 10 kg box lifted with 60 N of force in the case of a horizontal movement and cannot be lifted off the ground in the case of a vertical moment.
What is acceleration?
The rate at which velocity and speed change over time is referred to as acceleration. When something moves faster or slower, it is said to be accelerating or decelerating in a straight line. The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. They are vector quantities, accelerations.
How do you solve acceleration?
According to Newton's second law of motion, an object's acceleration is equal to the net force applied to it divided by its mass, or a = F m. This equation for acceleration can be used to calculate an object's acceleration when the mass and net force acting on it are known.
Briefing :
According to Newton's second law, a body's net force is equal to its mass times its acceleration.
F = m a
The force that the Earth uses to pull something toward it is its weight.
W = m g
F - m g = ma
a = F / m - g
Let's apply this equation to each situation:
A. box of mass 10 kg and applied force F = 60 N
a = 60/10 - 9.8
a = -3.8 m / s
B. Mass of the box 20 kg and the force 60N
C. Mass 20 kg and force 40N
D. Mass 10 kg and F = 40 N
We can see that the force in each situation is insufficient to lift the box off the ground.
Newton's second law applies if we assume that the motion is horizontal.
F = ma
a = F / m
We apply to each case:
A) m = 10 F = 60 N
a = 60/10
a = 6 m / s²
B) m = 20 kg and F = 60n
a = 60/20
a = 3 m / s²
C) m = 20 kg and F = 40 N
a = 40/20
a = 2 m / s²
D) m = 10 kg and F = 40 N
a = 40/10
4 m / s²
If there is an acceleration in the case of a horizontal movement, the cases are ranked from highest to lowest.
A> D> B> C
Using Newton's second law, we can conclude that the system's highest acceleration is:
1) Force cannot raise the box off the ground in the case of a vertical moment.
2) For horizontal motion, the system that accelerates at the greatest rate is:
A. a 10 kg box lifted with 60 N of force.
