Answer #1

Mass of the engineer conducting the train = M = 96 kg

Initial speed of the train = V1 = 5 m/s

Radius of the curve = R = 9 m

Centripetal acceleration of the engineer = a1

a1 = 2.778 m/s2

Centripetal force on the engineer = F1

F1 = 266.67 N

New increased speed of the train = V2

Centripetal force on the engineer at this new speed = F2

F2 = 682.67 N

a) Centripetal acceleration of the engineer = 2.778 m/s2

b) Centripetal force on the engineer = 266.67 N

c) Centripetal force on the engineer if the velocity of train was increased to 8 m/s = 682.67 N

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...
