What is the direction of impulse delivered to a bouncing ball?

[synergix]

Homework Statement

To make a bounce pass, a player throws a 0.60 kg basketball towards the floor. the ball hits the floor with a speed of 5.4m/s at an angle of 65^o to the vertical. The ball rebounds elastically with the same speed and angle. Calculate impulse (magnitude and direction) delivered to the ball by the floor.

Homework Equations

if ^ is delta
I=^P

The Attempt at a Solution

^V_x=0

^V_y=V_yf-V_yi=

5.4m/s(cos(65^o)+5.4m/s(cos(65^o)

Impulse= ^P

I just want to confirm that the impulse delivered to the ball will all be directed vertically upward because ^V_x=0. So the angle of collision will have no effect on the direction of impulse in this case.

The direction remains the same, but the magnitude depends on the angle.
