When a high-speed passenger train traveling at vP = 153 km/h rounds a bend, the engineer is shocked to see that a locomotive has improperly entered onto the track from a siding and is a distance D = 847 m ahead (see the figure). The locomotive is moving at vL = 28 km/h. The engineer of the passenger train immediately applies the brakes. Assume that an x axis extends in the direction of motion. What must be the constant acceleration...

An airplane heads due west at a speed 150 km/h relative to the wind. If the wind is moving at 30 km/h toward the north, what is the speed of the airplane relative to the ground? A jet airliner moving initially at 300 mi/h due east enters a region where the wind is blowing at 100 mi/h in a direction 30◦ north of east. What is the speed of the aircraft relative to the ground? A certain river is 0.5...

4.) An unmarked police car, traveling a constant 95 km h , is passed by a speeder traveling 145 km h . Precisely 1.00 s after the speeder passes, the policeman steps on the accelerator. If the police car’s acceleration is 2.00 fracms2 , how much time elapses after the police car is passed until it overtakes the speeder (assumed moving at constant speed)? 5.) Assume in Problem 4 that the speeder’s speed is not known. If the police car...

Consider a 1,233 kg car cruising at constant speed of 71 km/h. Now the car starts to pass another car, by accelerating to 119 km/h in 7 s. Neglect air drag and friction and assume the road is level. By taking the entire car as the system and appying an energy balance, determine the additional power (kW) needed to achieve this acceleration to 1 decimal place. (note: 1 m/s = 3.6 km/h)

The car with 20000 N weight increases its speed uniformly from 18 km/h to 90 km/h in 40 s up the inclined rough road with 15 angle and the coefficient of kinetic friction between the car and the ground is k = 0.5. Determine: ▪ the maximum power that must be supplied by the car engine ( = 0.8), ▪ the average power supplied by the engine. ▪ the initial kinetic energy T1 ▪ the final kinetic energy T2 ▪...

Centripetal Acceleration: A car moving with a constant speed of 80 km/h enters a circular, flat curve with a radius of curvature of 0.50 km.  If the friction between the road and the car’s tires can support a centripetal acceleration of 1.20 m/s2, without slipping, does the car navigate the curve safely, or does it fly off the road? Perform calculations to justify your answer. Be sure to perform all the necessary dimensional conversions to mks units.
