Question

A man of mass 30 kg uses a rope to climb which bears only 450 N.The maximum acceleration with which he can climb safely.......

• A. $10m/se{c}^2$
• B. $15m/se{c}^2$
• C. $20m/se{c}^2$
• D. $25m/se{c}^2$

Answer 1

The correct option is (C). $15m/se{c}^2$.

Given data,

Mass$=30kg$

Force$=450N$

acceleration$=?$

As we know,

$Force=mass\times acceleration$

$\Rightarrow 450=30\times a$

$\Rightarrow 450=30a$

$\Rightarrow a=\frac{450}{30}$

$\Rightarrow a=15m/s^2$.
