Question

A 3-kg object is being pushed to the right along a friction surface (no friction). The applied force that pushes the object to the right has a magnitude of 45 N. What is the acceleration of the object?

A. 15 m/s²
B. 10 m/s²
C. 5 m/s²
D. 20 m/s²

Answer 1

To calculate the acceleration of a 3-kg object being pushed with a 45 N force, you apply Newton's second law of motion: F = ma, which yields an acceleration of 15 m/s².

Step-by-step explanation:

To calculate the acceleration of the object, we will use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). Given that the force provided is 45 N and the mass of the object is 3 kg, we can rearrange the equation to solve for acceleration, a = F/m.

Substituting the provided values: a = 45 N / 3 kg = 15 m/s². Therefore, the acceleration of the object is 15 m/s².
