Vedclass · Answer

(a)

Taking boy, toy and ground as a composite system, we can say that there is no external force acting on the system, net acceleration of the system is zero.

$A_{	ext {system }}=0 \Rightarrow\left(F_{	ext {net }}ight)_{	ext {system }}=0$

$\Rightarrow F +(m g)_{	ext {boy }}+(N)_{	ext {ground }}+(f)_{	ext {friction }}=0$

A small child tries to move a large rubber toy placed on the ground. The toy does not move but gets deformed under her pushing force $F$, which is obliquely upward as shown in the figure.Then,
