A grave digger digs a grave with a varying force F equals 10 plus s squared Newtons, where s is in millimeters. The resulting force of the shovel is at about 30 degrees away from the tangent line from the curved motion path of the shovel. If he already shoved dirt at a curve's displacement of 150 millimeters per shove, and he did about 158 shove counts already, determine the grave digger's work done in kilocalories. 300
