Two forces, of magnitude F1 = 80.0 N and F2 = 45.0 N, act in opposite directions on a block which sits atop a frictionless surface. Initially, the center of the block is at position xi = -1.00 cm. At some latertime, the block has moved to the right, and its center is at a new position, xf = 2.00 cm.

(a) Find the work W1 done on the block by the force of magnitude F1= 80.0 N as the block moves from xi = -1.00 cm to xf = 2.00 cm.

(b) Find the work W2 done by the force of magnitude F2= 45.0 N as the block moves from xi = -1.00 cm to xf = 2.00 cm.

(d) Determine the change, K_f - K_i, in the kinetic energy of the block as it moves from xi = -1.00 cm to xf = 2.00 cm.
