Awesome that helps a lot! I know how to do it now, other than I am unsure about how to find the velocity before and after. I have never seen the velocities in x and y coordinates like that before. Would it be vx= -5-8= -13 m/s ; vy= 6-8= -2 m/s for a Δv (-13-(-2))/2 = -5.5 m/s ?
Oh yes I am sorry for leaving that out. I know the equations, but no I am not entirely sure on how they relate to one another. I read through my notes and am only confused.
Homework Statement
A ball of mass m= .25kg is moving with an initial velocity of \vec{v}=(8.0\hat{x}+8.0\hat{y})(m/s). It rebounds from a wall and has a final velocity (after impact) of \vec{v}= (-5.0\hat{x}+6.0\hat{y})(m/s)
a.) Determine the impulse exerted on the ball by the wall...
