# Homework Help: Acceleration, a kid, a sled and frictionless surface

A child sitting on a sled is pulled by a rope along a frictionless surface. The child and the sled weigh 214 N and the horizontal force on the sled is 53 N. What is the acceleration of child and sled?

I am new and in the process of printing and posting the PDF flyer at my local community college. Kudos to the Admin here for putting together.

okay... I am trying to solve simply by going 214cos(53), 214sin(53) also trying to use the basic 4 kinematic equations but have hit a wall. A friend told me about this forum so here I am.

What does the 214N actually represent? What direction does it act?

128.79 ?

Things to consider:

1) How are force and acceleration related?
2) What does the "weight" represent?
3) What are the implications of the frictionless surface?

Hi Trigulus, http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif [Broken]

What are the units associated with that number?
