A cardinal (Richmondena cardinalis) of mass 3.70×10−2 kg and a baseball of mass 0.144 kg have the same kinetic energy. What is t
he ratio of the cardinal's magnitude pc of momentum to the magnitude pb of the baseball's momentum?
2 answers:
Answer:

Explanation:
Since the cardinal and ball have the same kinetic energy, it is possible to determine the ratio between speeds. (c for cardinal, b for baseball)



The ratio is obtained by multiplying each side by
:


The value of this ratio is:

Given required solution
M=10kg W=? W=Fd
v=5.0m/s F=mg
t=2.40s =10*10=100N
S=VT
=5m/s*2.4s
=12m
so W=12*100
W=1200J
Change in position of object = Displacment
The correct answer is visible light.
