What net force (in N) gives a mass an acceleration of ?
Answer and explanation
Correct answer: C. 4
- Step 1: Newton's second law of motion dictates that the net applied force equals mass times acceleration: .
- Step 2: Substitute mass and acceleration : .
- Step 3: Multiplying the quantities gives .
Answer
4.
Why not the others: 40 multiplies by 10; 5 is an arithmetic error; 1 divides mass by acceleration ().
