A 64.5 kg person steps off a 129 kg rowboat with a force of 34.0 N. What is the force (in N) that is applied to the person by the rowboat?

would it be newton's 3rd law, meaning that the answer is 34 N?

Yes - for every action there is an equal and opposite reaction. Perfect.

@ybarrap are you sure it's not 64.5 * 9.81 + 34N = 667 N

shamim · Answer

U know according to newtons third law of motion
Action=reaction
Right?

shamim · Answer

But given 
Action=74N
Reaction=?

shamim · Answer

Reaction=74N
Right?

ybarrap · Answer

@Summersnow8 , the question indicates that the net force of the person to the boat is 34N. This net force is the response of the boat to the person.
