Answer:

a=1.672\ m.s^{-2}

Explanation:

Given:

  • mass of the object, m=35\ kg

forces by two mutually perpendicular ropes of the attached to the object:

  • F_x=20\ N
  • F_y=55\ N

<u>Now we find the resultant force effect due to the two given forces:</u>

F=\sqrt{F_x^2+F_y^2}

F=\sqrt{(20)^2+(55)^2}

F=58.52\ N

<u>Now the acceleration will be due to this resultant force:</u>

a=\frac{F}{m}

a=\frac{58.52}{35}

a=1.672\ m.s^{-2}
