The solution displays a diagram and good explanations to arrive at an answer.
Total acceleration of a body moving on a curve
A train slows down as it rounds a sharp horizontal turn, slowing from 90 km/h to 50 km/h in the 15 s that it takes to round the bend. The radius of the curve is 150 m. Compute the acceleration at the moment the train speed reaches 50 km/h.View Full Posting Details
