The answer is 3, 240J
KE=1/2 m v^2
KE= 1/2(45kg)(12m/s)^2
KE=1/2*45*144
KE= 3, 240 Joules

Which equation represents ohm's law?
Literally, ohm's law implies that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R).
Mathematically, this can be represented as:
Convert the expression to an equation
Multiply both sides by R to make V the subject
Reorder
<em>Option (a) is correct; Others are not</em>
Answer:A)
Explanation:
Well It makes the Most sense. The momentum of the Cars were lessened due to the hit.
B is wrong because not only did the red car crash but so did the blue so the real answer should be both.
C makes no sense at all.
D The momentum is lost after collision so it is not the same, so this is false also.
HOPE THIS HELPS! :)
