Question 206: Laws of Motion

Question

A block of mass $M$ is pulled along a smooth horizontal surface with a rope of mass $m$ by force $F$. The acceleration of the block will be

Accepted Answer

When a block of mass $m$ is pulled along smooth horizontal surface with rope of mass $m$ by force $F$, then $(M+m)$ will be the total mass of the system.
$$\begin{array}{ll}
	herefore & F=(M+m) a \
\Rightarrow & a=\frac{F}{M+m}
\end{array}$$

Answer

$\frac{F}{(M-m)}$

Answer

$\frac{F}{(M+m)}$

Answer

$\frac{F}{m}$

Answer

$\frac{F}{M}$
