Easiest way quite frankly is not worry about speed and angle.

Use Xspeed and Yspeed

When the ball hits the bat may yspeed = -yspeed, and adjust the xspeed depending on where on the bat the ball hits.

Open in online IDE

Graphics 400,300,0,2

x#=200
y#=150
xd#=Rnd(-2,2)
yd#=Rnd(-2,2)

SetBuffer BackBuffer()

Repeat

	; draw screen
	Cls
	Text x,y,"O",True,True
	
	; update location
	x=x+xd
	y=y+yd
	
	; bounce of sides
	If x<0 Then xd=-xd
	If x>400 Then xd=-xd
	If y<0 Then yd=-yd
	If y>300 Then yd=-yd
	Flip
