Question

A system containing three objects, which is initially at rest, accelerates by the application of a net force. Masses and time dependent position vectors of objects are given as;

m₁ =1 kg, m₂ = 5 kg, m₃ =7 kg

r1→r1→ = (t³ - 2)i^i^ + 2j^j^

r2→r2→ = (3 - t)i^i^+ 2j^j^

r3→r3→= 2i^i^+ (t - 4)j^j^

Find the magnitude of the net force of the system, F_net, as time t=2 s. (Your result must be in Newtons. No need decimal place and no error is accepted in your answer.)
