A block slides on a frictionless table to the right, which is dened as the positive xdirection. At time t = O, the object is at X0 = 4 m and is moving with a velocity v:: = 6 m/s. Aforce pushes the subject to the right, as shown in the gure. The force is not constant. It changes with time in such a way that the power delivered to the object is constant (always the same). At the t = D. the force has a magnitude of 5 N. What is the power delivered to the block in Watts and is the block's acceleration increasing, decreasing, or constant
