At B after doing components of velocity in horizontal and vertical direction we get,
vx = vcos50 and vy =  vsin50 respectively.
Hence change in velocity in x and y direction respectively are =>
Vx = vcos50 – 0
and
Vy = vsin50 – v => v(sin50 – 1)
Net Velcity from vector addition,
Vnet = Vx + Vy
Hence,
Vnet = v(sin50 – 1 +  vcos50)
