Question 240: Laws of Motion

Question

A body,  under the action of a force $\overrightarrow F  = 6\widehat i - 8\widehat j + 10\widehat k,$ acquires an accelerations of 1 m/s
2
. The mass of this body must be

Accepted Answer

$\overrightarrow F  = 6\widehat i - 8\widehat j + 10\widehat k$
$\left| {\overrightarrow F } ight| = \sqrt {36 + 64 + 100} $
$ = \sqrt {200} N = 10\sqrt 2 N$
Acceleration, a = 1 m s
Ã¢ÂÂ2
$ 	herefore $ $Mass,\,M = {{10\sqrt 2 } \over 1} = 10\sqrt 2 \,kg$

Answer

10 kg

Answer

20 kg

Answer

10$\sqrt 2 $ kg

Answer

2$\sqrt {10} $ kg
