At the highest point of the projectile, only x component of the velocity will be there.

velocity \:  =  Vx = V cos  \:  \beta
velocity = 15cos45 = 15 \times  \frac{1}{ \sqrt{2} }  =  \frac{15}{ \sqrt{2} }

jazzzz1: how to find resultant please give formula
TPS: In this, there is no need for resultant. If you want to find the velocoty at any time t during flight, find the x and y component separately and add the two vectors to find the resultant (velocity at time t)

Answer:

At the maximum height only velocity the projectile gets is in the x direction

Explanation:

velocity =  v{x} = vcos \beta  = 15 \cos(45)  =  \frac{15}{ \sqrt{2} }  \\  ie \: velocity =  \frac{15 \sqrt{2} }{2}

happy to help
