Answer to Question #334337 in Classical Mechanics for isha

Question

A car with passengers has a mass M=2000 kg and travels with a speed of 65 miles/hour.

Suddenly, the driver the brakes to avoid a collision with another car traveling at 20 miles/hour at a distance D=30 meters away (98.4ft). Analyze the problem from the moment when the breaks are fully engaged and tires are not rotating.

Question: will there be collision between the two cars?

Talk about the friction and how would you determine if there will be collision.

you need to solve the problem as a function of the friction coefficient, then discuss your result based on the following coefficient’s values : {0.1, 0.8}. What should be the minimum safe distance between the two cars [assuming two values for the coefficient {0.1, 0.8}?

The solution needs to include the following:

1. All diagrams (if any).

2. Show detailed solution steps including all the calculations.
