Question

Using what we know about Newton's Second Law of Motion, let's say that on the way to work, your teacher's car breaks down. Your teacher's car weighs 1,000kg. As your teacher uses all of their might to push the car, the car moves 0.5m/s. Knowing Mr. Newton's Second Law of Motion, calculate how much force your teacher is using, in Newtons, of course. Make sure you are using: F=ma.

a) 200 N
b) 400 N
c) 800 N
d) 1000 N

Answer 1

According to Newton's Second Law of Motion, the force your teacher is using to push the car is 500 N.

Step-by-step explanation:

To calculate the force your teacher is using to push the car, we can use Newton's Second Law of Motion, which states that force (F) is equal to mass (m) times acceleration (a). In this case, the mass of the car is 1,000 kg and its acceleration is 0.5 m/s². So the force your teacher is using can be calculated as:

F = ma

F = 1,000 kg * 0.5 m/s²

F = 500 N

Therefore, your teacher is using a force of 500 Newtons to push the car.

To calculate the force your teacher is using to push the car, we need to use Newton's Second Law of Motion, which states that the force exerted on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

However, the question does not provide the acceleration but instead gives the velocity (0.5 m/s).

To find the force using the given velocity, we would need to know the time over which that velocity was achieved from rest, or any additional information regarding the change of velocity to find the acceleration. Since this information is not provided, we cannot accurately calculate the force based on the information given.
