# what are the works of power which affect the mass?

$\setminus \textrm{P o w e r} = 12.635 \setminus k W$

#### Explanation:

The power $P$ of work on the block of mass $m = 1400 \setminus k g$ moving with a constant velocity $v = 1 \setminus \frac{m}{s}$ up the plane inclined at an angle $\setminus \theta = \setminus {\tan}^{- 1} \left(\frac{3}{4}\right)$ is given as

$P = \setminus \textrm{\to t a l f \mathmr{and} c e a c t \in g o n t h e b l o c k \mathrm{do} w n t h e p l a \ne} \setminus \times \setminus \textrm{v e l o c i t y}$

$P = \left(m g \setminus \sin \setminus \theta + \setminus \mu m g \setminus \cos \setminus \theta\right) v$

$= m g \left(\setminus \sin \setminus \theta + \mu \setminus \cos \setminus \theta\right) v$

$= \left(1400\right) \left(9.81\right) \left(\frac{3}{5} + \left(0.4\right) \frac{4}{5}\right) \setminus \cdot 1$

$= 12635.28 \setminus W$

$= 12.635 \setminus k W$
