Answer:
the correct answer is c, they will accelerate away from each other at different speeds. the 80kg will go faster due to less mass
Answer:
m = 9795.9 kg
Explanation:
v = 35 m/s
KE = 6,000,000 J
Plug those values into the following equation:

6,000,000 J = (1/2)(35^2)m
---> m = 9795.9 kg
B an egg released from the ovary. It’s probably wrong
Answer:
Friction 100 j
Explanation:
Friction causes the inequality between PE and KE
100 J
