Experiment scenario: Taylor is testing three brands of fertilizer to see which produces the best plant growth. The amount of water given to each plant will remain the same. He plans to use only one
type of plant as well.
Questions: His measurement (the plant height will be his
variable. The
amount of water he waters them with will be one of his
variable. The three
brands of fertilizer he uses are his
variable.

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.)
