Q1) Calculate the traction torque required at the wheels and the corresponding rotational speed of the wheels in revolution per minute (rpm) for a vehicle with the following data (4 marks): a. $\mathrm{mass}(\mathrm{m})=1200\mathrm{kg}$ b. Frontal area $\left(A_f\right)=2.2{\mathrm{m}}^2$ c. Coefficient of drag $\left(C_d\right)=0.2$ d. Vehicle speed $(\mathrm{V})=100\mathrm{km}/\mathrm{h}$ e. Wheel size $=195/65/15$ f. Coefficient of rolling $\left(C_r\right)=0.012$ g. Density of air $(?)=1.2\mathrm{kg}/{\mathrm{m}}^3$ h. Acceleration of gravity $(\mathrm{g})=9.8\mathrm{m}/{\mathrm{s}}^2$
