At a sharp horizontal circular turn a train slows down going from 90.0 km/h to 50.0 km/h in the 15.0 s it takes to round the bend. The radius of the curve is 150 m. Assume the train continues to slow down at the same rate. At the moment the train speed reaches 50.0 km/h calculate: the magnitude and direction of the tangential acceleration. the radial acceleration (magnitude and direction). the magnitude and direction of the total acceleration. (a)A car on a highway is heading toward a cloverleaf interchange with a circular curvature or Radius=50 m, traveling at a steady speed of 14m/s. A) determine the position and velocity of the vehicle at points A and B. B) determine the vector components and direction of the average acceleration during the trip from a to b. Include a sketch of the vector showing it's orientation. SPeciffy the direction between -180 degrees and 180 degrees as measured from the +x axis.

T(t) = (cos t, sin t, t) : at t = TCross country runners must turn a corner around a tree obstacle, in the rain. a) The first runner takes a wide line to the tree and runs around a curve with a radius of 1.5 m and undergoes a radial acceleration of 10 m/s2. Determine their tangential velocity during the curve. b) The second runner is trying to catch up and so runs closer to the tree. If a loss of control (slip) occurs at a radial acceleration of 22 m/s2, does the runner manage to run around a curve with a radius of 0.50 m at a tangential velocity of 3.5 m/s?a) Which particle follows the smaller circle, b) does the particle travel clockwise or counterclockwise?
