Homework Statement
A testing laboratory wants to determine if a new widget can wistand large accelerations and decelerations. to find out, they glue a 5.0 kg widget to a test stand that will drive it vertically up and down. the graph shows its acceleration during the first second, starting from rest.
[I can't really put the graph on here, but basically its an acceleration-time graph, the initial acceleration is 19.6 m/s^2 (at t=0), and at the end of the graph (t=1) the acceleration is -19.6 m/s^2, with acceleration = 0 at the halfway point (t=1/2)]
a) identify the forces acting on the widget and draw a free-body diagram
b) determine the value of Ny, the y-component of the normal force acting on the widget, during the first second of motion. give your answer as a graph of Ny vs TThe attempt at a solution
There are actualy more parts to this question, however my issue is that I don't really understand the set-up of the situation.. from my understanding, the bottom of the object is glued onto a test stand, which moves up and down. if this is the case, shoudln't the entire normal force be in the Y-direction anyway? The question seems to imply that there is also an x-component as well.
any thoughts?
