A.
first law
B.
second law
C.
third law
D.
law of gravity

Answer 1

B . Second law

Step-by-step explanation:

According to second law:

Net Force acting on the body produce acceleration. The magnitude acceleration of the body is directly proportional to net force and inversly proportional to the mass.

Mathematically:

a =
`(F)/(m)`

and

F = ma

So according to the given condition Waldo should use Second law.
