What net force (in N) gives a mass an acceleration of ?
Answer and explanation
Correct answer: C. 8
**
- Step 1: By Newton's second law of motion, the net force acting on a body of mass undergoing acceleration is .
- Step 2: Substitute mass and acceleration : .
- Step 3: Compute the product: .
Answer
8.
Why not the others: '1/2' divides mass by acceleration () instead of multiplying; '6' adds mass and acceleration () instead of multiplying them; '80' introduces an extra factor of , confusing acceleration with .
