Give the y and y components of its change in momentum --> ∆Px and ∆Py

are the following correct?

M= 0.135 kg

Vx = 30.0 m/s

θ=45

Vy=30.0 m/s

I calculated ∆Px = M*Vx*cos 45

0.135 * 30.0 * cos 45 = 2.9 kg m/s

∆Py = M*Vy*sin 0

= 0.135*30.0*sin 0 = 0

but I got it wrong..

can anyone help me???

thanks..
