Train A is traveling at a constant speed VA = 36 mi/hr while car B travels in a straight line along the road as shown at a constant speed V A conductor C in the train begins to walk to the rear of the train car at a constant speed of 4 ft/sec relative to the train. If the conductor perceives car B to move directly westward at 11 ft/sec, how fast is the car traveling?

A motorcycle patrolman starts from rest at A two seconds after a car, speeding at the constant rate of 120 km/h, passes point A. If the patrolman acceler- ates at the rate of 6 m/s² until he reaches his maxi- mum permissible speed of 150 km/h, which he maintains, calculate the distances from point A to the point at which he overtakes the car. 120 km/h

Train A is traveling at a constant speed VA = 35 mi/hr while car B travels in a straight line along the road as shown at a constant speed VB. A conductor C in the train begins to walk to the rear of the train car at a constant speed of VC/A = 4 ft/sec relative to the train. If the conductor perceives car B to move directly westward at VB/C = 15 ft/sec, how fast is the car traveling? B UB | N x C

Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 8 ft/s2 . It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 15 ft/s2.Determine the minimum distance d between the cars so as to avoid a collision.
