the coefficient of static friction between steel train wheels and steel rails is .58. the engineer of a train moving at 140 km/h spots a stalled car on the tracks 150 meters ahead. if he applies the brakes so that the wheels don't slip, will the train stop in time?
a car traveling east (uphill) on University Avenue andslamming on the brakes would accelerate west at 8 meters per secondsquared, and a car traveling west would accelerate east at 5.9meters per second squared. Find the stopping distance for eachdirection if the speed just at the brakes are applied is 20 m/s(about 45 miles per hour).
A car is traveling 80 km/hr in a school zone. A police car startsfrom rest just as the speeder passes it and accelerates at aconstant rate of 8 km/hr. When does the police car catch thespeeding car? (hint: These two equations are helpful: d= s * t andd = ΓΒ½ a t^2)*t^2= t squared*
