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...

An automobile traveling at speed v on a level surface approaches a brick wall. When the automobile is at a distance d from the wall, the driver suddenly realizes that he must either brake or turn. If the coefficient of static friction between the tires and the surface is µ, what is the minimum distance that the driver needs to stop (without turning)? What is the minimum distance that the driver needs to complete a 90◦ turn (without braking)? What...

You are called as an expert witness to analyze the following auto accident: Car B, of mass 1900 kg, was stopped at a red light when it was hit from behind by car A, of mass 1500 kg. The cars locked bumpers during the collision and slid to a slop with brakes locked on all wheels. Measurements of the skid marks left by the tires showed them...

Could you please show your work as well? Thank you!
A cup of coffee is on a table in an airplane flying at a constant altitude and a constant velocity. The coefficient of static friction between the cup and the table is 0.29. Suddenly, the plane accelerates forward, its altitude remaining constant. What is the maximum acceleration that the plane can have without the cup sliding backward on the table? m/s

Problem-1 Nardine is traveling southbound on a level section of the 15 freeway with speed up = 60mi/hr. Joshua is also traveling southbound a distanced directly behind Nardine with the same speed to 60mi/hr. Nardine has ABS brakes in her car, and Joshua does not have ABS brakes in his car. On this section of the freeway, Nardine's tires have coefficients of friction (M ) (0.7,0.5) and Joshua's tires have coefficients of friction of Walk) = (0.5, 0.3). Nardine suddenly...

24) How much work is performed by friction in slowing a 10kg object from 4 m/s to 2 m/s? 25) To avoid an accident, you slam on your brakes, skidding for a distance of 40 m before you stop. (Your anti-lock brakes were malfunctioning!). Assuming a coefficient of kinetic friction of 0.8 between your tires and the road, how fast were you going before slamming on the brakes? 26) A 1-kg block is held below a vertically mounted spring -...
