T. 24. The block shown above is pulled over a rough horizontal surface by the tension force T in the string. The velocity of the block does not change and therefore it may be correctly inferred that (A) the inertial mass of the block is infinite (B) the inertial mass of the block is zero (C) the force due to friction and the tension are equal in magnitude (D) the block will continue to move at a constant velocity if T is reduced to zero (E) this constant velocity condition can be maintained by a tension of any desired value Unauthorized copying or reuse of any part of this page is illegal. -145-
