Homework Statement
I did:
P1x = 7 * 0.5 = 3.5 kg m/s ; P1y = 4*0.5 = 2 kg m/s => P1 = sqrt (3.5^2 + 2^2) = 4.03N*s
so P2 = 2.92 kg m/s ; and P3 = 2.69 kg m/s
then the question #2 is:
P1 + P2 = sqrt (4.03^2 + 2.92^2) = 4.98 kg m/s
P1 - P2 = I have no ideas.
Is my work correct? and please help with P1 - P2.
Thanks!
