On a freeway entrance ramp, you accelerate your \(1200-\mathrm{kg}\) car from \(5 \mathrm{~m} / \mathrm{s}\) to \(20 \mathrm{~m} / \mathrm{s}\) over \(500 \mathrm{~m}\). Having an open lane, you continue to accelerate at the same (constant) rate for another \(500 \mathrm{~m}\). Is your final speed \(35 \mathrm{~m} / \mathrm{s}\), less than \(35 \mathrm{~m} / \mathrm{s}\), or greater than \(35 \mathrm{~m} / \mathrm{s}\) ?
