Asystem 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 = 3 kg, m3 =6 kg - (t3 - 4); + 33 - (4 - t) + 33 3- 33+ (t - 3)} Find x-componenent of position vector of system's enter of mass, r comx, as time t=5 s. (Your result must be in meters and include 2 digit after the decimal point. Maximum of 2% of error is accepted in your answer.)
