Answer 1

Pt.2 assume the driver has a mass of $75.7\,\mathrm{kg}$.

What horizontal force does the seat exert on the driver?

Answer in units of N

avg acc=46.1403

avg force=41230.97208

**Solution:**

$$a = 46.1403\,\frac{\mathrm{N}}{\mathrm{kg}} \quad \text{- acceleration of the car};$$ $$m = 75.7\,\mathrm{kg} \quad \text{- mass of the driver};$$

Newton's second law for the driver along the X-axis:

$$x: F_{\text{seat} \rightarrow \text{driver}} = ma = 75.7\,\mathrm{kg} \cdot 46.1403\,\frac{\mathrm{N}}{\mathrm{kg}} = 3493\,\mathrm{N}$$

**Answer:** horizontal force that seat exert of the driver is $3493\,\mathrm{N}$.
