Physics Question
Two toy ducks, attached to each other by a
string, are being pulled by a very happy guy
who just got them as a graduation present
(Fig. 4.31). The front duck is 5.0 kg and the
back duck is 2.0 kg. If the happy guy pulls
them with a force of 10 N and there is no
friction, calculate
a) the acceleration of both ducks.
chapter 4: Newton’s Fundamental Laws 147
b) the tension in the string connecting duck 1
and duck 2.
