Question

17. A force = = (10i – 6 +8k) Newton produces an
acceleration of 1 m/s in a body of mass m. Find mass m.
Va) 14.14 kg . (b) 18.18 kg
(©) 20.21 kg
(d) 56 kg
The form​

Answer 1

Answer:

a) 14.14

Explanation:

$f = \sqrt{ {10}^{2} } + \sqrt{ {6}^{2} } + \sqrt{ {8}^{2} }$

$f = \sqrt{200} = 10 \sqrt{2}$

$f = ma$

$m = \frac{f}{a}$

$m \: = \frac{10 \sqrt{2} }{1}$

$m = 10 \times 1.414 = 14.41kg$
