- Homework Statement
- Two students sit in a sled and slide down a hill which gives them an initial horizontal velocity of 9.2 m/s. Their combined mass is 120 kg and the coefficient of friction between the sled and the snow is 0.23. How far will they slide horizontally before coming to a stop?

- Relevant Equations
- Ek=mv2/2

a=fnet/m

vf2=vi2+2aavd

-began by finding Fnet=Fg-Ff

=1176-270.48

=905.52

acceleration = 905.52/120 kg

=7.546 m/s2

sub numbers into vf2=vi2+2aavd

-got an answer of -5.6m

so clearly it,s wrong because displacement should not be negative in this case
