2. A large fish with a mass of 1-kg is in motion at 45 cm/s when it encounters a smaller fish
(m=0.25 kg) that is at rest. The large fish
swallows the smaller fish and continues in
motion at a reduced speed. Fill in the before-
and after-collision table below.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
