Newton's Second Law of Motion (F = ma)Quiz - Solve & Score
Q1. A trolley of mass 2 kg is pushed so that it speeds up at 3 m/s^2. What net force acts on it?
- A.6 N
- B.0.667 N
- C.5 N
- D.1.5 N
Answer: A. 6 N
By Newton's second law F = m*a = 2 kg * 3 m/s^2 = 6 N.
Q2. What net force is needed to give A wooden block of mass 5 kg an acceleration of 4 m/s^2?
- A.0.8 N
- B.1.25 N
- C.9 N
- D.20 N
Answer: D. 20 N
By Newton's second law F = m*a = 5 kg * 4 m/s^2 = 20 N.
Q3. A loaded cart having a mass of 8 kg accelerates at 2.5 m/s^2 along a smooth floor. How large is the unbalanced force on it?
- A.0.312 N
- B.10.5 N
- C.20 N
- D.3.2 N
Answer: C. 20 N
By Newton's second law F = m*a = 8 kg * 2.5 m/s^2 = 20 N.
