A river of width' a' with straight parallel banks flows due north with speed u. The points O and A are on oppositebanks and A is due east of O. Coordinate axes Ox and Oy are taken in the east and north directions respectively. Aboat, whose speed is v relative to water, starts from O and crosses the river. If the boat is steered due east and uvaries with x as : u = x(a – x)Find :the displacement of boatman when he reaches the opposite bank from the initial position.

Given: The speed of the water is u=xa-xva2 north ward. The velocity of the boat relative to water is…

Problem 3-44a: Three vectors A, B, and C have X components of -7.0, -3.0, 0.0, respectively, and y components of -3.0, 5.0, 8.0, respectively. Find the magnitude of A + B + C. Problem 3-44b: Find the direction of A + B + C in degrees. (NOTE: angles are entered as values between 0° and 180°.)
It takes a golfer a total of three strokes to put the ball in the hole. The displacements of the three strokes are as follows: d, = 4.20 m the north, d, = 2.10 m northeast, and d, = 1.10 m at 6 = 30.0° west of south, as shown in the figure. If the golfer had made the hole in a single shot, what would be the displacement of the ball? (Assume the positive y- and x-axes are in the north and east directions, respectively.

At a football game, imagine the line of scrimmage is the y-axis. A player, starting at the y-axis, runs 8.50 yards, back (in the −x-direction), then 15.0 yards parallel to the y-axis (in the −y-direction). He then throws the football straight downfield 55.0 yards in a direction perpendicular to the y-axis (in the +x-direction). What is the magnitude of the displacement (in yards) of the ball? yards (b) What if? The receiver that catches the football travels 64.0 additional yards at an angle of 45.0° counterclockwise from the +x-axis away from the quarterback's position and scores a touchdown. What is the magnitude of the football's total displacement (in yards) from where the quarterback took the ball to the end of the receiver's run?
A car comes to a bridge during a storm and finds the bridge washed out. The driver must get to the other side, so he decides to try leaping it with his car. The side the car is on is 20.3 mm above the river, whereas the opposite side is a mere 1.6 mm above the river. The river itself is a raging torrent 57.0 mm wide.
