Question #6: c is not the right answer

Top View F(N) 5.0 1 (8) P 6. Two blocks, of mass m and 2m, are initially at rest on a horizontal frictionless surface. A force F is exerted individually on each block, as shown above. The graph shows how F varies with time t. Which block has the greatest average power provided to it between t = 0 s and t = 3 s? a. Block m b. Block 2m c. Both blocks have the same power provided to them d. Can't determine without the displacement
