Final Answer:
1. Acceleration: symbol = *a*, unit = m/s²
Force: symbol = *F*, unit = N (newton)
Mass: symbol = *m*, unit = kg

2. Triangle: top = *F*, bottom left = *m*, bottom right = *a*

3. a. 8 N
b. 450 N
c. 54 N
d. 2500 N

4. 132 N

5. 9800 N (downward; weight = *mg*)

6. 250 N

7. mass = *F* / *a*
acceleration = *F* / *m*

8. a. 2.4 kg
b. 8 kg
c. 0.2 kg
d. 6 kg

9. a. 4 m/s²
b. 0.5 m/s²
c. 1.6 m/s²
d. 1.67 m/s² (≈ 1.7 m/s²)

10. 10 m/s²

11. 50 kg

12. 40 m/s²

13. a) 32 N
b) 160 m/s²

14. Net force = 2.85 N downward; acceleration ≈ 9.5 m/s²

15. 4 m/s²
