- At an accident scene on a level road, investigators measure a car's skid mark to be 78 m long. It was a rainy day and the coefficient of friction was estimated to be 0.30. use these data to determine the speed of the car when the driver slammed on (and locked) the brakes. (why does the car's mass not matter?)At an accident scene on a level road, investigators measure a car's skid mark to be 102m long. The accident was occurred on a rainy day, and the coefficient of kinetic friction was estimated to be 0.36. Use these data to determine the speed of the car when the driver slammed on (and locked) the brakes.A car is moving at 20 m/s along a horizontal road has its brakes suddenly applied and eventually comes to rest. What is the shortest distance in which it can be stopped if the friction coefficient between tires and road is 0.90? Assume that all four wheels brake identically. If the brakes don't lock the car stops via static friction.
- Can you help me solve this problem please? Assume no frictionA car is moving at 50 mph initially on the road, then the engine suddenly shut down and the car continues to roll for 100 meters before it comes to a full stop. Calculate the frictional coefficient of the road.At an accident scene on a level road, investigators measure a car's skid mark to be 88 m long. It was a rainy day and the coefficient of friction was estimated to be 0.35. a.)Use these data to determine the speed of the car when the driver slammed on (and locked) the brakes. Express your answer to two significant figures and include the appropriate units.

What is the largest cofficient of friction that he could successfully push against if he slides the crate up at a constant speed? (This question has been already answered, don't answer) What minimum coefficient of friction would be necessary to hold the crate in the other question on the same ramp without it sliding down at all, with no help from the Stevedore?
