Solve 2 **Physics Problem-Solving Example****Problem 1**:If the speed of a car is increased by 66%, by what factor will its minimum braking distance be increased, assuming all else is the same? Express as a percent increase.**Solution**:1. Explanation: When a car's speed increases, its kinetic energy increases, which in turn increases the braking distance. The braking distance is directly proportional to the square of the speed.**Problem 2**:Investigators measured a car's skid mark to be 91 meters long. The coefficient of kinetic friction was estimated to be 0.54. Determine the speed of the car when the driver slammed on the brakes.**Solution**:1. Explanation: The speed can be determined using the formula derived from physics principles involving motion and friction.**Note**: There is a partial text covered by the hand, rendering the rest of the sentence unreadable. This might contain an additional problem or continuation of the notes. ---This text is a transcription of handwritten physics problems and their solutions. The handwriting involves problem-solving steps for applying concepts of speed, kinetic friction, and braking distance.
