force acting on a particle moving in the xy plane is given by = (2yi + x^2 j ),

Question

force acting on a particle moving in the xy plane is given by = (2yi + x^2 j ), where is in newtons and x and y are in meters. The particle moves from the origin to a final position having coordinates x = 4.40 m and y = 4.40 m, as in the figure below. (a) Calculate the work done by on the particle as it moves along the purple path (OAC). J (b) Calculate the work done by on the particle as it moves along the red path (OBC). J (c) Calculate the work done by on the particle as it moves along the blue path (OC).

Explanation / Answer

(a) from O to A the x force is zero, so the work iszero
