A force F = (3x + 5y), 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 = 4.70 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 (4.70 m, 4.70 m) along a straight-line path making an angle of 45.0 with the positive x-axis.
