Answer:
Before collision:
momentum to right = .14 * 3.5 = .49 kg m / s
momentum to left = .62 * 4.81 = 2.98 kg m / s
Total momentum = .49 - 2.98 = - 2.49 to left
M V = -2.49 net momentum to left
V = -2.49 / (.14 + .62) = -3.28 m/s to left
Answer:
A. the pancake that forms is a different state of matter.
Explanation:
because the pancake mix is liquid ,and when you cook it you for a solid.
-It takes air from it's surroundings.
-Compresses the air
