1. A 1900 kg car traveling at a speed of 24 m/sskids to a halt on wet concrete where μk = 0.50. a. How long are the skid marks in meters.? 2. For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 40mph? Suppose that μs=1.00 and μk=0.80. 3. A 17 kg crate is placed on a horizontal conveyor belt. The materials are such that μs = 0.43 and μk= 0.25. a....

A 1500 kg car skids to a halt on a wet road where Mk = 0.54. How fast was the car traveling if it leaves 60-m-long skid marks?
A 1200 kg car traveling at 60 mph quickly brakes to a halt. The kinetic energy of the car is converted to thermal energy of the disk brakes. The brake disks (one per wheel) are iron disks with a mass of 4.0 kg. Estimate the temperature rise in each disk as the car stops. Express your answer using two significant figures.
A car is traveling down a hill that makes an angle of 17° with the horizontal. The driver applies her brakes, and the wheels lock so that the car begins to skid. The coefficient of kinetic friction between the tires and the road is μK = 0.53. (a) Find the acceleration of the car. (Take down the ramp to be the positive direction) (b) How long does the car take to skid to a stop if its initial speed is...

How much force does an 72kg astronaut exert on his chair while sitting at rest on the launch pad? B. How much force does the astronaut exert on his chair while accelerating straight up at 14m/s2 ? 3. A. A 4000 kg...
This Question: 1 pt Skid mark analysis is one way to estimate the speed a car was traveling prior to an accident. The speed, that the vehicle was traveling in mies per hour can be approximated by the formula 330df, where d represents the length of the skid marks in feet and represents the drag factor of the road. A vehicle that was involved in an accident on an asphalt road was traveling ata speed of 75 mph when it...
A race car is traveling at a constant speed of 102 m/s around a circular track with a radius of 3250 m. How long does it take the race car to go around the track once? Express your answer in seconds.
