A cat that weighs 55 N sits on the top of a cat tree. It is 2 m above a 110N dog. How does the mass of the animals relate to the force of gravity on
them?
A. The 55 N cat has less mass than the 110 N dog.
B. The mass of the 55 N cat will be the same as the mass of the 110
N dog after it jumps to the ground.
C. The mass of the 55 N cat is greater than the mass of the 110 N
dog.
D. The 55 N cat has the same mass as the 110 N dog when it is in the
cat tree.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
