A girl is sitting in a sled sliding horizontally along some snow (there is friction present). The mass of the girl is 28.4 kg and the mass of the sled is 15.3 kg.
The force of friction acting on the sled as it slides is -96 N.
If the sled has an initial velocity of 41.8 m/s, and it slides for 3.76 seconds before it hits a wall.
(Ignoring the unfortunate mess with the wall) How much work did friction do during this time?
*Hint: you cannot solve the problem in 1 step with the current information, you will need to find acceleration, and use time to find something else before you can find an answer!
