Question
mike is in a boat in the middle of a lake, and cathy is in a second boat next to mikes boat. if mike pushes off on cathy's boat with a force f in the positive x direction what can be said of the force on mikes boat and his boats acceleration? (ignore resistive forces of the water on the boats)
a. mike experiences a force F in the negative direction and his acceleration will be half of cathys
b.mike experiences a force of F in the positive direction and his acceleration will be half of cathys
c. mike experiences a force of 1/2 F in the negative direction and his acceleration will be half of cathys
d. mike experiences a force of F in the negative direction and his acceleration will be 2 times that of cathys
e. mike experiences a force of 1/2 F in the negative direction and his acceleration will be 2 times that of cathys
Explanation / Answer
Correct answer is d
applying newton's third law every action has an equal and oppsite reaction. and as it is exerting force on other boat it's acceleration has to be greater than the other ones.
