Question

CALCULATI ACCELERATIA UNUI CORP PE CARE ACTIONEAZA O FORTA PE VERTICALA IN SUS. F= 30 N, DACA MASA CORPULUI ESTE DE 2 KG. g=10m/s2

foarte urgent multumesc

Answer 1

$\bf a =\dfrac{\Delta v}{\Delta t} = \dfrac{F}{m}$

$\bf F=30\, N$

$\bf m=2\, kg$

$\bf a=\dfrac{F}{m} =\dfrac{30\, N}{2\, kg} =\dfrac{30\dfrac{kg\cdot m}{s^2} }{2\,kg}$

$\bf a=\dfrac{30\dfrac{m}{s^2} }{2} =\boxed{\boxed{\bf 15\dfrac{m}{s^2} }}$

Bafta! :)
