A car mass $1000\text{ kg}$ braking on a flat road from speed $v = 20\text{ m/s}$ stops in $25\text{ m}$. When travelling downhill on a slope, gravity provides a forward force along the slope of $2000\text{ N}$. Assuming the brakes apply the same braking force as on the flat road, what is the braking distance downhill from $20\text{ m/s}$?

• A$25.0\text{ m}$
• B$33.3\text{ m}$
• C$41.7\text{ m}$
• D$50.0\text{ m}$
