What impulse is needed to change the velocity of a 90.0 kg football player from 3.6 m/s towards the north and make it 1.2 m/s toward the northeast? In what direction must the force be exerted?

2. Relevant equations

p=mv

3. The attempt at a solution

I drew vectors of the two momentums and found the resultant momentum to be 410N.s @ 11 E of N

but the answer in the back of the book is 259N.s 17 E of S

I can't think of any other way to approach this problem...
