Explanation / Answer

              Given      1)              vx = 6 m/h   = 6 / 3600m/s                                          = 0.0016 m/s                     vy = 8 m / h = 8 / 3600                                       = 0.0022 m/s        natvelocity    V   = (vx)2 + (vy )2                                  = (0.0016 )2 + ( 0.       2) v = 50 ft /s               1ft = 0.3048 m              v = 50 x 0.3048 m/ s                 =   15.24 m/s          angle = 60deg           vx = v cos                = 15.24 x cos 60                = 7.62 m/s           vy= v sin               = 15.24 x sin 60               =13.1982 m/s                                  2) v = 50 ft /s               1ft = 0.3048 m              v = 50 x 0.3048 m/ s                 =   15.24 m/s          angle = 60deg           vx = v cos                = 15.24 x cos 60                = 7.62 m/s           vy= v sin               = 15.24 x sin 60               =13.1982 m/s
