Question

(a) A force F = (2xi + 5yj), where F is in newtons and x and y are in meters, acts on an object as the object moves in the x-direction from the origin to x = 5.23 m. Find the work W = F · dr done by the force on the object (in J). (b) What If? Find the work W = F · dr done by the force on the object (in J) if it moves from the origin to (5.23 m, 5.23 m) along a straight-line path making an angle of 45.0° with the positive x-axis. Is the work done by this force dependent on the path taken between the initial and final points? dependent independent
