That is what I wanted to confirm, as some of the responses wanted me to give an answer and justify it and I was getting more confused each time I looked at the question and thought that there was a correct option.
But I don't think everyone on the forum thinks that this question and option...
The last reply says that the question is wrong and so can't be answered.
Can ~I have comments from physics experts on if this is a viable question as it stands and if so what the correct option is or if its impossible to answer?
I know the answer to the physics question but don't understand the...
friction provides centripetal force so if no friction the man would slide radially. Sill can't see how to figure it out. To me the question is vague and and have assumed the paths is a right angle for simplicity rather than a circle although a slight curve is obviously needed.
thanks
The centripetal force which acts inwards. But the man is in the air and as he and train are moving North just before he jums he carries on moving North in the air.
It states 'sharp bend' so am assuming this means that the track curves very quickly to make a right angle ie a small curve. Irrespective of speed, when the man jumps and assuming the train quickly turns to the right , the speed of the man in the North direction is greater than that of the train...
using the lettering in the diagram, not the one given in the first description, I actually think he would land on c or D. The reason is that initially, as shown in diagram the train is due North just before man jumps so the man travels due North in the air. The speed determines if he lands...
ok.
The train is initailly moving staright(north) as the man jumps and then suddenly it moves to the right round sharp bend. The momentum of man keeps him moving North in the air. So both C and D are possibilities depending on the speed of the train.
Thanks
