1. A car leaves skid marks 85 meters long. It slows down at a rate of 4m/s^2. How fast was the car traveling?
Again, totally confused. Don't know where to start.

To calculate the speed of a car, you can use the formula: Speed = (Stopping distance x Deceleration) / 2. You will need to know the stopping distance in meters and the deceleration in meters per second squared.
The safe deceleration rate for a car depends on various factors such as the road conditions, weather, and type of vehicle. However, on average, a deceleration rate of 7-8 meters per second squared is considered safe for most cars.
Yes, the speed of a car can be determined if only the stopping distance is known. However, other factors such as the weight of the car, road conditions, and braking efficiency will also affect the speed calculation.
The higher the speed of a car, the longer its stopping distance will be. This is because the car will have more kinetic energy that needs to be dissipated through braking, resulting in a longer distance required to come to a complete stop.
No, the deceleration rate can vary depending on the type and condition of the car. Factors such as the weight, tire condition, and braking system can affect the deceleration rate of a car. Additionally, the driver's reaction time and braking technique can also impact the deceleration rate.
