Two students are in-line skating. The diagram below shows student S pushing student T. Student S has a mass of 60 kg, and student T has a mass of 40 kg. Student S Student S is pushing student T in a straight line with a force equal to the friction on student T's skates. Which of the following must happen if student S continues to pus student T with the same force? O Student T will travel in a circle. Student T will speed up Student T O Student T will slow down O Student T will move at a constant velocity
