Three vector are oriented as shown in figure below where. A=20.0units, B=40.0units, And C=30.0. (a) The x and Y component of the resultant vector. (b) The magnitude of the resultant vector. (c) Direction of the resultant vector ​ { please help me}

Explanation:

a). Vertical component of vector B = Bsin(45)

                                                     = 40sin(45°)

                                                     = 28.28 units

Horizontal component of vector B = Bcos(45°)

                                                         = 40cos(45°)

                                                         = 28.28 units

Vertical component of vector C = Csin(45°)

                                                     = 30sin(45°)

                                                     = 21.21 units

Horizontal component of vector C = Ccos(45°)

                                                         = 30cos(45°)

                                                         = 21.21 units

Vertical forces = A + Bsin(45°) - Csin(45°)

                       = 20 + 28.28 - 21.21

                       = 27.07

Horizontal forces = Bcos(45°) + Ccos(45°)

                             = 28.28 + 21.21

                             = 49.49 units

b). Magnitude of resultant force =

                                                =

                                                = 56.41 units

c). Direction of the resultant force → Along vector B (at an angle of 45° from the horizontal line)

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

force tends to be low and long diustance masses are high
