Work Done by a Variable Force
A 2 kg object moving along the x-axis is subjected to a force described by the function F(x) = (4 - e^(-x/2)) N. What is the work done by this force as the object moves from position x = 0 m to x = 4 m?
A
16 - 2(1 - e^(-2)) J
B
16 J
C
4(1 - e^(-2)) J
D
16 + 2(1 - e^(-2)) J
