1. The problem statement, all variables and given/known data This is a not hard question but you may imagine a image in your mind since I can't provide you the diagram: A 10-kilogram object at rest at point A. The object accelerates uniformly from point A to point B in 4 seconds. (A and B is a straight line. A..........B) The object then moves up the incline. (Neglect friction. So at the point B on there is the incline,the end point of the incline is D. so the incline is BD. Imagine a right triangle, BD is the hypotenuse, the vertical height is S) Question: The object comes to rest at a vertical height of S (point D) when the angle of incline is 30, If it increases to 40, the object would come to rest at a vertical height 1) less than S , 2) greater than S, 3) equal to S 3. The attempt at a solution I chose 2) since if you draw a 40 degree angle, and at the same time you need to keep BD the same distance, so the vertical distance is larger than before. But my teacher said it was 3). I don't get it. Hope you can give me some idea.
