Why would someone volunteer to help students take on a student that changed their name every one minute? Could it be the student is answer grazing?
The childs weight has two components, down the slide, normal to the slide.
down the slide=mg*sinTheta
normal to slide=mg*cosTheta
so
net force = m*a
mg*sinTheta-mu*mg*cosTheta= ma
solve for mu.
A child goes down a playground slide with an acceleration of 1.24 m/s^2.
Find the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 32.0 degrees below the horizontal.
