1. Vpa = 180m/s. @ 0 deg.

Vag = 40m/s @ 120 deg, CCW.

Vpg = Vpa + Vag,

Vpg = (180 + 40cos120) + i40sin120,

Vpg = 160 + i34.64,

Vpg=sqrt ((160) ^2 + (34.64) ^2) = 163.7m/s.

2. tanA = Y / X = 34.64 / 160 = 0.2165,

A = 12.2 deg, CCW. = 12.2deg. North of

East.

3. 1 hr = 3600s.

d = Vt = 163.7m/s * 3600s = 589,320m.
