Q15. As shown in the image below, a man starts from point A, and tries to swim across a 40-ft wide river to point B on the other side, downstream at a distance d. The river flows with a constant velocity v, = 2.6 ft/s, with direction shown in the image. The man can swim at a speed vm/r = 6.0 ft/s in still water (which is the relative constant speed with respective to the flowing water). If the distance d = 43 ft, determine the magnitude of the man's absolute speed vm (with the effect of the flowing water) so he can arrive at point B. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. d d B.

During the middle of a family picnic, Barry Allen received a message that his friends Bruce and Hal needed to be saved. Barry promised his wife Iris that he would be back in exactly 5 minutes. From that that picnic location, Barry runs at a speed of 600 m/s for 2 minutes at a heading of 35° north of west to save Bruce. He then changed his heading to 30° west of north, slows down to 400 m/s and runs for 1 minute to save Hal. (The changes in speed are essentially instantaneous and not part of solving this problem).(a) Draw a physical representation of the displacement during Barry’s full trip.(b) Use the Related Quantities sense-making technique to compare Barry’s total distance traveled to themagnitude of his displacement.(c) What average velocity (magnitude and direction) does Barry need to return back to the picnic inorder to keep his promise to Iris?
an automobile starting from rest speeds up to 12 m/s with a constant acceleration of 1.2 m/s^2. runs at fast speed for some time, and finally comes to rest with a decelaration of 1.5 m/s^2. if the total distance travelled is 319m, find the total time required. draw the v-t and s-t curves.
A jet is flying straight and level at a speed v0 = 1300 km/h when it turns to change its course by 90° as shown. In an attempt to progressively tighten the turn, the speed of the plane is uniformly decreased in time while keeping the normal acceleration constant and equal to 8g, where g is the acceleration due to gravity. At the end of the turn, the speed of the plane is vf = 800 km/h. Determine the radius of curvature ρf at the end of the turn and the time tf that the plane takes to complete its change in course. The radius of curvature ρf at the end of the turn is ___ m.(Round the final answer to one decimal place.) The time tf that the plane takes to complete its change in course is ___ s. (Round the final answer to four decimal places.)
