A particle starts from a point A at an angle 60 degrees with AB. At the same time,another particle starts from B at an angle of 30 degrees with BA with a velocity of 10kmh^-1 and meets the 1st particle after some time.Find the velocity of the 1st particle.(in kmh^-1)
The answer is 5.77.

Vparticlle cosx=Vat the slider so; VpCOS30=10 so ; Vp=11.547 so Vs=11.547cos60 =5.77 km/h
