A 62 kg man is ice-skating due north with a velocity of 6.6 m/s when he collides with a 43 kg child. The man and child stay together and have a velocity of 3.2 m/s at an angle of 33° north of due east immediately after the collision. What are (a) the magnitude and (b) the direction (as an angle measured from due East) of the child's velocity just before the collision?

I start walking. The 1st leg of my trip I walk dA = 55 m at θA = 15° south of east. The 2nd leg of my trip I walk dB = 120 m at θB = 21° north of east. On my final leg I walk dC = 75 m at θC = 56.5° north of west. Choose the coordinate system so that x is directed towards the east, and y is directed towards the north. A.) Write an...
