الله يجزاكم الجنة اريد حل المسأله ضروري الاختبار قريب
if mass 752 kg
three forces Fm=Ft=Fc=80.5 N
اوجد التسارع في الحالتين :
الاولى
-write out the X component for each of the three forces
-sum the x components of force
-divide by the mass to find ax since ax is positive ,the accleration is to the right ,as expected
الحاله الثانية اوجد:
-again start by writing the x compent for each forces
-sum the x components of force
-solve for ax in this case ax is negative .indicating an acceleration to the left
