A 1500 sedan goes via a broad intersection traveling from north to south if it is strike by a 2300 SUV traveling from east to west. The two cars become enmeshed due to the impact and slide as one thereafter. On-the-scene measurements illustrate that the coefficient of kinetic friction between the tires of the cars and the pavement is 0.750, and the cars slide to a halt at a point 5.42 west and 6.49 south of the impact point.
i) Explain how fast was sedan traveling just prior to the collision?
ii) Explain how fast was SUV traveling just prior to the collision?
