The net force applied to it is 6311.9 N.
To calculate the net force to the car, first, we need to find the acceleration using the equation of motion.
Force: This as be defined as the product of mass and acceleration of a body. The S.I unit of force is Newton (N)
⇒ Formula
- S = ut+at²/2................. Equation 1
⇒ Where:
- u = Initial velocity
- S = Distance
- t = Time
- a = acceleration
From the question,
⇒Given:
- S = 40 m
- t = 3.0 s
- u = 0 m/s (at rest)
⇒ Substitute these values into equation 1
⇒ Solve for a
- 9a = 80
- a = 80/9
- a = 8.89 m/s²
⇒ To get the force, we use the formula below
- F = ma .................... Equation 2
⇒ Where:
- F = Force applied
- m = mass of the car
⇒ Given:
⇒ Substitute these values into equation 2
Hence the net force applied to it is 6311.9 N.

Answer:
The answer is A.
Explanation:
To measure a temperature, you have degrees with Farenheight or Celsius. Meters are measured with a meter stick while grams and kilograms are measurments for weight.
Therefore, degrees Celsius is your answer.
Best of Luck to you!
Is proportional to the CHANGE.
hope this helps
According to Newton`s law. Force exerted by car,
After adding an additional 400 kg of mass, the force will be same therefore the acceleration
Thus, the acceleration after adding the masses is 1.47 \ m/s^2.
Answer:
All fraction of kinectic energy is lost to barrel of a spring gun of mass 1.8 kg
Explanation:
A ball of mass 0.50 kg is fired with velocity 160 m/s ...
The kinetic energy is given by 1/2mv²
Kinectic energy of the ball = 1/2 *0.5*160²
Kinectic energy = 1/4 *25600
Kinectic energy = 6400 joules.
If no energy is lost to fiction, and the ball sticks to a barrel of a spring gun of mass 1.8 kg with initial velocity zero, all kinetic energy is lost to the barrel of a spring gun of mass 1.8 kg.
