A child goes down a playground slide that is inclined at an angle of 28.0° below the horizontal. Find the acceleration of the child given that the coefficient of kinetic friction between the child and the slide is 0.415
Heres what I have so Far:
F - fk = ma
mgsin0 - MkN = ma
mgsin0 - Mkmgcos0 = ma
gsin0 - mkcos0 = a
so by this,
a = 9.8sin28 - .415cos28
= 4.2343
I cannot figure out what I am doing wrong here
thanks friends
