A sled of mass 13.4 kilograms is pulled along flat snow-covered ground. The static friction coefficient is 0.334, and the kinetic friction coefficient is 0.111.
I solved both part a and b, but im having trouble with part c.
c. Once moving, what force is needed to accelerate the sled 2.69 meters per second per second?
The Attempt at a Solution
Im confused on how to do this.
So Its asking for the force pushing the sled forward. Using the formula am=f
if i plug in acceleration and the mass i get 13.4x2.69=36.046, but it said it was wrong.
Am I missing something? Do I need to factor in frictional force?
Would I add 14.6 to 36.046? 14.6 is the force needed to push the object at a constant velocity.
