When Push Comes to Shove
3 of 10
Two forces, of magnitudes $F_1 = 95.0 \text{ N}$ and $F_2 = 20.0 \text{ N}$, act in opposite directions on a block, which sits atop a frictionless
surface, as shown in the figure. (Figure 1) Initially, the center of the block is at position $x_i = -4.00 \text{ cm}$. At some later time, the
block has moved to the right, and its center is at a new position, $x_f = 6.00 \text{ cm}$.

Part A
Find the work $W_1$ done on the block by the force of magnitude $F_1 = 95.0 \text{ N}$ as the block moves from $x_i = -4.00 \text{ cm}$ to
$x_f = 6.00 \text{ cm}$.
