B)5.3 N
C)53 N
D)64 N
E)More information is needed.

The maximum weight of the cartoon character is 1.3 N. This is because the thrust obtained from firing the bullets is equal to the weight of the character. The thrust is given by the equation F = mv, where F is the thrust, m is the mass of the bullets, and v is the velocity of the bullets. The weight of the character is given by the equation W = mg, where W is the weight, m is the mass of the character, and g is the acceleration due to gravity. Setting these two equations equal to each other, we get:F = Wmv = mgv = gSubstituting the given values into this equation, we get:v = 9.8 m/sThe thrust is then given by:F = mvF = (0.016 kg)(9.8 m/s)F = 0.1568 NThe weight of the character is then given by:W = FW = 0.1568 NTherefore, the maximum weight of the cartoon character is 0.1568 N, which is approximately 1.3 N.
