Question

You’re investigating a crash in which a 1640-kg Nissan Leaf electric car and a 3220-kg Toyota Land Cruiser SUV collided at right angles in an intersection. The combined wreckage skidded 20.0 mm before stopping. You measure the coefficient of friction between tires and road and find it to be 0.697. Show that at least one car must have exceeded the 70-km/h speed limit at the intersection. You’ll need to consider each car separately, assuming that it was at the speed limit and finding the other car’s speed, which you should report in your answer.

Part A: Assuming that the Nissan moved at the speed limit, find the Toyota’s speed. Express your answer in kilometers per hour.

Part B: Assuming that the Toyota moved at the speed limit, find the Nissan’s speed. Express your answer in kilometers per hour.
