Calvin is pulling Hobbes on his sled with a force of 45 N [30o above the ground]. The mass of Hobbes
and the sled is 18 kg and the coefficient of friction between the sled and the ground is 0.25.
Determine a) the net force in the vertical.
in this case is the net force going to equal 0 ?
i got net force 176.4 N is that right? what i did was
fnet=ma
fnet= 18(9.8)
=176.4
