Question

. A student needs to calculate the acceleration of an object. The problem gives the object's mass and the net force acting on it. Which problem-solving methodology should the student use?

• A. Qualitatively describing the relationship between force and acceleration, rather than performing precise calculations.
• B. Identifying the correct formula (F=ma) and rearranging it to solve for the unknown variable.
• C. Setting up a physical experiment to measure the acceleration directly under the given conditions.
• D. Searching for pre-solved problems with similar parameters and adapting their solutions.

Answer 1

Answer:

B. Identifying the correct formula (F=ma) and rearranging it to solve for the unknown variable.

• This is the correct problem-solving methodology.

• The student must first identify Newton's second law, then rearrange it to solve for acceleration (a=F/m), and finally substitute the given values to find the answer.
