A football player runs for a distance d, = 8.67 m in 1.25 s, at an angle of 0 = 57.3 degrees to the 50-yard line, then turns left and runs a distance d, = 12.52 m in 1.51 s, in a direction perpendicular to the 50-yard line. The diagram shows these two displacements relative to an x-y coordinate system, where the x axis is parallel to the 50-yard line, and the y axis is perpendicular to the 50-yard line. What is the magnitude of the total displacement, in meters? What angle, in degrees, does the displacement make with the y axis? (Note that the angle e was given as measured from the x axis rather than the y axis.) What is the magnitude of the average velocity, in m/s? What angle, in degrees does the average velocity make with the y axis? (Note that the angle 0 was given as measured from the x axis rather than the y axis.)

A rifle at A is fired at a target at B. If the speed of the bullet is 1400 ft/s, determine the rectangular form of the velocity vector v.
I would like to know the answer to the questions and how you managed to obtain them. As shown on the coordinate system, points A and B have the following distances from the origin: xA = 3.10 ft , zA= 2.30 ft , xB = 2.80 ft , yB = 1.40 ft , and zB= 1.60 ft. 1) For the two points A and B, what are the i, j, k components of the position vector that starts at A and ends at B? (Figure red) 2)A wire is connected to two supports. (Figure green) The support on the wall has coordinates xA= 3.35 ft and zA= 3.35 ft . The support on the ground has coordinates xB= 1.12 ft and yB= 4.05 ft . What are the i, j, k components of the unit vector u that describes the line of action from point A to point B?
sdasOne morning, Cfonnie walks from her house to go to a store that is 500 ft, S 40o W from her house. She starts walking 120 ft, SW; then continues walking 100 ft, 10o S of E; then sees a friend who is 700 ft, 30o N of E from where she is. What is her friend’s location, (magnitude and direction) relative to her house? (Ans. 667.54 ft, 21.79o N of E)show complete solution and diagrams
A hiker leaves the camp, and using the compass, walks 4 km E, then 10 km S, 6 km E, 7 km N, 12 km W, and finally 10 km N. After three days, the hiker goes astray. Using a diagram, find all the sides and angles after the hiker's walk. Remember to make the diagram and identify the vectors.

In a hockey game, player A passes the puck to player B, who is standing on the blue line, as shown in the diagram. The y axis is perpendicular to the blue line, and the x axis is parallel to the blue line, as shown. The puck travels a distance d1 = 21.6 m on its way to player B, making an angle θ = 40.8 degrees with the x axis. Player B then passes the puck so that it moves a distance d2 = 6.5 m on the blue line, in the negative x direction. What angle, in degrees, does the total displacement make with the y axis?
A sailboat race course consists of four legs, defined by displacement vectors A, B, C and D. The magnitudes of the first three vectors are A=3.0km, B=5.50km, and C=4.50km. The finish line of the course coincides with the starting line. What is the distance of the fourth leg and the Angle.
Two cars A and B are stopped at a traffic light, waiting for the light to change from red to green, see Figure 3. Car B is 6 meters behind car A. When the light changes to green, car A leaves accelerating at a rate of 0.3 m / sec2, while car B departs 2 seconds later and accelerates at a rate of 0.8 m / sec2. Determine the position where they are next to each other, measured from the “o” point.
The kinematic equation of a material point motion along a straight line (x- axis) has the form x = A + Bt + Cr, where A = 4 m, B = 2 m/s. C= -0.5 m/s?
