As a driver in a car traveling at 60 km/hr approaches an intersection, the light suddenly changes. The driver applies the breaks until the car stop. If the vehicle (plus driver) mass is 1075 kilograms and the deceleration is constant over the 5 seconds of stopping, calculate the average force that acts at the points of tire-to-road contact.
As a driver in a car traveling at 60 km/hr approaches an intersection, the light suddenly changes. The driver applies the breaks until the car stop. If the vehicle (plus driver) mass is 1075 kilograms and the deceleration is constant over the 5 seconds of stopping, calculate the average force that acts at the points of tire-to-road contact.
For an actual event, constant deceleration would be unusual. Here we solve 'however so the deceleration" might vary over the 5 seconds.
