forcesF,andg, is momentarily at rest at x - 0 at t 0. It is acted upon by twoA particle of mass m momenF2 It is given that F, 70 j Nin the direction as shown. What third force, F , is required to make the acceleration of the particleand F2 is unknown. The particle experiences a constant acceleration azero? (Note: sine 4/5, cose 3/5, and tane 4/3. Neglect gravity.)a-10m/ผู้F,(A) 30i+ 40j(B)-(301+40)(C) 40i + 30j(D)-(401+30j)

Answer»

option 2 when we write -30,-40 in vectorial form-(30i+40j)

for reference.
