Q. When a high-speed passenger train traveling at 148 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 = 605 m ahead. The locomotive is moving at 21 km/h. The engineer of the high-speed train immediately applies the brakes.What must be the magnitude of the resulting constant deceleration if a collision is to be just avoided?

Q. A 69 kg boy and a 40 kg girl use an elastic rope while engaged in a tug-of-war on an icy, frictionless surface. If the acceleration of the girl toward the boy is 3.0 m/s2, find the magnitude of the acceleration of the boy toward the girl.
