A block of mass m 2kg is pulled along a rough horizontal surface by applying a constant force at an angle (tan^-1 2) with the horizontal as shown in the figure. The friction coefficient between the block and the surface is u= 0.5. if the block travels at a uniform velocity v=5 m/s then calculate the average power (Watt) of the applied force. (Take acceleration due to gravity g- 10 m/s m.
