As a van climbs a 35 ° slope at 60 m/s, its driver falls ill and takes his foot off the accelerator pedal. The van stops after 75 m. Since the ill driver cannot use the foot brake and hand brake, the truck starts to move downhill after a moment's stop. After the van slides 40 meters downhill, the driver begins to brake. Since the braking force is 0.5W (W = weight); a- What is the kinetic friction coefficient between the road and the van? b- Calculate the total time it takes until the van comes to the point where the driver got sick while going down the hill. 35°

You have devised an experiment to measure the kinetic coefficient of friction between a ramp and a mass. You place the mass on the ramp at an angle high enough that the mass starts sliding. You measure the time it takes to fall down a known distance. The time it takes to fall down the 45 degree ramp starting from a standstill is At = 0.46 sec, m=1 kg, and the distance it falls, Ax , is 0.5 m. What is µk? m Дх in At Uk
You are driving through the Ouachita Mountains at 12m/s. You see a maple-leaf oak (Quercus acerifolia) crossing the road and hit the brakes, 20m away.
