what happens if an athlete is pulling a sled angle attached to his hip, resulting in an angle of force of pull at 15 degrees to the ground. If the coefficient of sliding friction between the sled and the grass is 0.8 and the sled has a mass of 25 kg, what is the acceleration of the sled if he is constantly pulling with a resultant force of 300 N?
