OK. He takes off from C. Thank you both @haruspex and @jbriggs444 for pointing that out. That's what I initially thought, but then before I wrote down the equations I thought I'd better recheck the statement of the problem and I looked at #1 which states that he takes off from A. I committed an error thinking that I caught myself in error. In short, a comedy of errors. Back to the drawing board.jbriggs444 said:How can we agree on a solution when we cannot even agree on the problem statement. Post #6 specifies a take-off at point C.
Jumping on a moving train can be dangerous and should only be attempted by experienced individuals. It is important to first assess the speed and direction of the train. Then, make sure to have a firm grip on the handrails or ladder and jump with your feet together, landing on the train with both feet at the same time. Avoid jumping onto a train that is traveling too fast or is in a curve.
It is important to wear appropriate clothing when jumping on a train. Avoid wearing loose or baggy clothing that could get caught on the train or hinder your movement. Opt for comfortable, close-fitting clothes and sturdy shoes with good traction.
No, it is not safe to jump on any part of the train. The best place to jump is on the ladder or handrails located on the side of the train. Avoid jumping on the front or back of the train, as these areas may be more unstable and dangerous.
Before attempting to jump on a train, it is important to familiarize yourself with the train and its speed. Practice jumping on and off stationary objects to improve your balance and coordination. It is also helpful to have a spotter who can guide you and help you time your jump.
Jumping on a train is considered trespassing and is illegal in most places. It is important to research and understand the laws and regulations of the area before attempting to jump on a train. It is also important to respect private property and obtain permission from the train company before attempting to jump on a train.
