Two blocks of different mass are connected by a string. The system is accelerated across a smooth horizontal surface by a force supplied by a rubber band connected to the less massive block. The tension in the connecting string will be zero The same as the force pulling the leading block O Less than the force pulling the leading block Greater than the force pulling the leading block Question 4 4 pts An elevator of mass 500 kg is caused to accelerate upward at 3.0 m/s2 by a force in the cable. What is the force, in Newtons, exerted by the cable? (Use g = 10 m/s2 )
