Resistive Forces Practice Test

Based on the scenario, a $1200,\text{kg}$ car travels at constant $25,\text{m/s}$ on level road with rolling resistance $F_r=\mu mg$, $\mu=0.020$; find $F_r$.

Considering the conditions described, a $90,\text{kg}$ cyclist rides at $v=8.0,\text{m/s}$ with air drag $F_d=kv^2$, $k=0.25$; what is the resistive force magnitude?
