Ответ:
Magnitude of resultant force is 1190.314 N
Direction of force is 13.352°
Explanation:
given data:
thrust force = 725 N
Angle = 32.4 degree
Let x is consider as positive direction
Resultant force in x direction is
Rx = 725 + 513cos32.4 = 1158.14 N
and Resultant force perpendicular to x direction is:
Ry = 513sin32.4 = 274.88 N
Magnitude of resultant force is
and resultant force direction is
