Please Thanks
C = -13.2 -i10.4. Q3.
tanAr = Y/X = -10.4/-13.2 = 0.78788,
Ar = 38.2 Deg. = Reference angle.
A = 180 + Ar = 180 + 38.2 = 218.2 Deg.,
CCW.
C = X/coswA = -13.2 / cos218.2 = 16.8 m/s @ 218.2 Deg.
B = 100 - i106. Q4.
tanAr = Y/X = -106 / 100 = -1.06,
Ar = -46.67 Deg.
A = Ar + 360,
A = -46.67 + 360 = = 313.3 Deg.
B = X/cosA = 100 / cos313.3 = 145.7 m/s
@ 313.3 Deg.
Use same procedure for last prob.
NOTE: 7.6 cm/s^2. Is t5hat an error?
The resultant will be in Q1.
