I'm having trouble getting which answer is correct and the explanation as to why, please help. Thanks!

Question: A sled is frictionlessly sliding a very long distance along a frozen river at a constant velocity. Some birds flying over see the sled and decide to land on it one at a time. If each lands on the sled, how will the velocity, kinetic energy, and momentum of the sled change as the birds land on the sled?


a)The velocity will decrease, but the kinetic energy and the momentum must stay the same.


b)The velocity and kinetic energy will increase, but the momentum will stay the same.


c)The velocity, kinetic energy, and momentum of the sled will all increase.


d)The velocity and kinetic energy will decrease, but the momentum will stay the same.


e)The velocity, kinetic energy, and momentum of the sled will all decrease.

Explanation / Answer

d)The velocity and kinetic energy will decrease, but the momentum will stay the same.
