Question

A student is testing Newton’s Second Law using an airtrack and suspended mass (m). Unfortunately, the student neglectsto level the air track. Amazingly, the student even forgets to turnon the air track, so there is considerable friction. The angle islarge enough to cause the motion to begin spontaneously. Compare toExample 5-4, page 158 and Example 5-5, page 160.

a.)        Draw a FBD for theglider on the air track. Compute x and y net force componentsacting on the glider. Use a coordinate system in which the+x axis points down the plane and the +y axis isvertically upward, perpendicular to the plane for thisFBD.

Fx,net=                      ______________________________________________________

Fy, net=                     ______________________________________________________

b.)        Draw a FBD for thesuspended mass, m. Show all forces acting on the mass. Use acoordinate system in which the +y axis points verticallydownward for this FBD.

Fy, net=                     ______________________________________________________

c.)        What is theacceleration of the glider? (Equation in terms of M, m, g, m,(among others)

Warning: Eliminate the tension, T, fromthe simultaneous equations.

Warning: Eliminate the friction andnormal force from the simultaneous equations.

Let m be the kinetic coefficient of friction.

ax=                ______________________________________________________
