The center оf mаss оf twо mаsses, A ([mа] kg) and B ([mb] kg), moves along the x-axis as a function of time, as shown in the figure. t1=0 and t2=10 s. At t = [t] s, mass A is located at position xA = 7 m. Determine the position xB of mass B. Provide the answer in meters. [Hint: use x=k×t to find x at t=4 s, where k is the slope.]
