An object of mass m has an initial velocity of u at point A, where it enters the fixed incline shown below. The kinetic friction coefficient between the object and the surface is μ 0.3. An instant after the object passes point B the normal reaction force from the supporting surface onto the object drops to one-half the value it had before reaching B. The distance d=4mm. Determine: a) the acceleration of the object just before reaching point B, b) the initial velocity u of the object at A.

Question

Hi, I have an engineering dynamics question.

An object of mass m has an initial velocity of u at point A, where it enters the fixed incline shown
below. The kinetic friction coefficient between the object and the surface is u=0.3. An instant after
the object passes point B the normal reaction force from the supporting surface onto the object
drops to one-half the value it had before reaching B. The distance d=4mm. Determine:
a) the acceleration of the object just before reaching point B,
b) the initial velocity u of the object at A.
Treat the object as a particle, neglecting its size and air resistance. Free body diagrams are
required as part of the solution.

C Mississippi Jane is at it again! The big bad evil one has trapped her on an accelerating conveyor belt with a rolling pipe - or so it seems. The pipe is actually not there and instead to be added in during post production for the actress' safety. It is up to you to calculate the proper physics of the pipe so that the CGI pipe may look as realistic as possible. If the pipe is meant to have a mass of 500 (kg) and a mean radius of 0.55 m, determine the pipe's angular acceleration if the conveyor belt has an acceleration of 1.9 Assume the pipe does not slip on the conveyor belt and neglect its thickness. m 82 α= 3.5 X rad 2 сс UBC Engineering
