A wagon is used to help deliver papers. There is a force applied at an angle of 25 degrees to the horizontal that causes the wagon to move a distance of 15m[N] in 10.0s from rest. There is a force of friction of 3.1 N acting on the 27kg wagon.
What is the acceleration of the wagon?

s=at^2/2
a =2•s/t^2 =2•15/100 = 0.3 m/s^2
