Explanation:

Step1: Recall Newton's second law

$F = ma$ (rearranged to $m=\frac{F}{a}$ for mass)

Step2: Substitute values for Q16

$m=\frac{36\ \text{N}}{3\ \text{m/s}^2}$

Step3: Calculate mass for Q16

$m=12\ \text{kg}$

Step4: Use Newton's second law for Q17

$F = ma$

Step5: Substitute values for Q17

$F=22\ \text{kg} \times 3.8\ \text{m/s}^2$

Step6: Calculate force for Q17

$F=83.6\ \text{N}$

Answer:

For Question 16:

Equation: $m=\frac{F}{a}$
Substitution: $m=\frac{36\ \text{N}}{3\ \text{m/s}^2}$
