Question: If a 5 kg object is subjected to a net force of 15 N, what is its acceleration?

Options:

Correct Answer: 3 m/s²

Solution:

Using Newton\'s second law, F = ma, we can find acceleration: a = F/m = 15 N / 5 kg = 3 m/s².

If a 5 kg object is subjected to a net force of 15 N, what is its acceleration?

If a 5 kg object is subjected to a net force of 15 N, what is its acceleration?

Step 1: Identify the mass of the object, which is 5 kg.
Step 2: Identify the net force acting on the object, which is 15 N.
Step 3: Recall Newton's second law of motion, which states that Force (F) equals mass (m) times acceleration (a), or F = ma.
Step 4: Rearrange the formula to solve for acceleration (a): a = F/m.
Step 5: Substitute the values into the formula: a = 15 N / 5 kg.
Step 6: Perform the division: 15 N divided by 5 kg equals 3 m/s².
Step 7: Conclude that the acceleration of the object is 3 m/s².

Newton's Second Law – This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
