The engineer of a passenger train traveling at 25.0m/s sights a freight train whose caboose is 200m ahead on the same track. The freight train is traveling at 15.0 m/sin the same direction as the passenger train. The engineer of the passenger train immediatly applies the brakes causing a constant acceleration of .100m/s^2 in adirection opposite to the trains velocity, while the freight train continues with constant speed. will there be a collision?

A train which is traveling at 73 mi/hr applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 56 mi/hr as it passes a point 1/2 mi beyond A. A car moving at 36 mi/hr passes point B at the same instant that the train reaches point A. In an unwise effort to beat the train to the crossing, t the driver "steps on the gas." Calculate the...

2) a ) A train passes a point, already traveling at 2.0 m/s and accelerating at 0.6 m/s / s . Write down the equation that describes the train’s position. A girl on her bicycle reaches that very point 4 seconds later and begins to ride at a constant velocity v in order to catch the train. Write down the equation that describes her position. b) Show that she will never catch the train if her velocity is 6 m/s...

A science student is riding on a flatcar of a train traveling along a stralght horizontal track at a constant speed of 12.0 m/s. The student throws a ball into the alr along a path that he judges to make an initial angle of 50.0 with the horizontal and to be in line with the track. The student's professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does she see the ball rise?...

A bicyclist who has a mass (including their bike) of 85 kg is racing around a track. The radius of curvature of the track is 20 m. The bicyclist’s linear velocity is 17 m/s. Given the bicyclist is at a constant speed, staying level (not going up or down, therefore no vertical acceleration), what angle does the track need to be banked so that NO frictional force is required to keep their circular path?

Part A. The sports car, having a mass of 1700 kg, is traveling
horizontally along a 20° banked track which is circular and has a
radius of curvature of ρ = 100 m. If the coefficient of
static friction between the tires and the road is
μs = 0.2 . Determine the maximum constant speed
at which the car can travel without sliding up the slope. Neglect
the size of the car.
