KINEMATICS QUESTION -- ATTEMPT IF YOU DARE
A passenger train is traveling at 30 m/s when the engineer sees a freight train 384 m ahead of his train traveling in the same direction on the same track. The freight train is moving at a speed of 6.1 m/s.
(b) If the engineer's reaction time is 0.87 s and the train loses speed at the minimum rate described in Part (a), at what rate is the passenger train approaching the freight train when the two collide?
(c) For both reaction times, how far will the passenger train have traveled in the time between the sighting of the freight train and the collision?
Answer from part a: 0.7696
I attempted part C too, but I'd like to wait for some help on B before I post my current work on C, if that's alright.
Thank you!
