This is my first time to use this template by the way.....(adsbygoogle = window.adsbygoogle || []).push({});

1. A hungry 12.5 kg predator fish is coasting from west to east at 70.0 cm/s} when it suddenly swallows a 1.15 kg} fish swimming from north to south at 3.60 m/s.

Find the magnitude of the velocity of the large fish just after it snapped up this meal. Neglect any effects due to the drag of the water.

Find the direction of the velocity of the large fish just after it snapped up this meal.

2.conservation of momentum, p=m/v

3. (12.5kg)(.7m/s)+(1.15)(3.6) = total momentum= 12.89, then i got the total mass by adding 12.5+1.15.... i use the equation p=m/v and solve for the veolicity.

I get the wrong answer here and I am not sure how to find the direction..

THANKS
