7. A 0.90 kg falcon is diving at 28.0 m/s at a downward angle of 35° (figure 3). It catches a 0.325 kg dove from behind in midair. What is their combined velocity after impact if the dove’s initial
velocity was 7.00 m/s directed horizontally?

Planck decided to assume that atoms could only vibrate at certain frequencies that were whole numbers eg 2f, 3f and so on. others used to think that atoms vibrate continuously

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.

Ibelieve the answer is arteries
