Question
As shown in the diagram below, a soccer player kicks a ball directly toward the goal along a displacement vector
, which has a length of 7.0 m and a direction 30 degrees east of south. Alternatively, she could have kicked it to a second player standing directly in front of the goal along a displacement ry, who could have then kicked it to the goal along a displacement vector rx, as shown. Find the magnitudes and directions of rx and ry.
As shown in the diagram below, a soccer player kicks a ball directly toward the goal along a displacement vector r , which has a length of 7.0 m and a direction 30 degrees east of south. Alternatively, she could have kicked it to a second player standing directly in front of the goal along a displacement ry, who could have then kicked it to the goal along a displacement vector rx, as shown. Find the magnitudes and directions of rx and ry.Explanation / Answer
rx = r*sin30 = 7*sin 30 = 3.5 m
direction is east
ry = r*cos30 = 7*cos 30 = 6.06 m
direction is south
