Two ropes are tied to opposite sides of a block that has a mass m = 1 kg on a frictionless surface. Suppose one rope pulls to the right with a force of 2 N while the other pulls to the left with 0.5 N. (a) Can you say anything about the velocity of the block? If so, what is the direction and magnitude? (b) Can you say anything about the acceleration? If so, what is the direction and magnitude? (c) Now suppose we don't know the value of the force to the left, but know the velocity of the mass follows that shown in the plot. Plot the value of the force to the left versus time. velocity (m/s) 3 2 time
