The force acting on an object varies in time is given. From the Force verse time graph and given mass and initial velocity, Dr. Hood calculates the impulse of the force and determines the velocity of the object after the force stops acting on it. Thus is #42 from Serway & Faughn by Holt 06Rev.

  • Two objects A and B, are connected by a rigid rod that has a length L. The objects slide along perpendicular guide rails (i.e. A slides along the X-axis and B slides along the Y-axis). If A slides to the left with a constant speed "v," find the speed of B when the angle between the rod and X-axis is 60º.

    Your answer should be in term of "v"

  • yay! Hood to the rescue! ^_^'

    I've never liked these graph thingys -_-' especially the one that we had in our first UT homework -_-' hahahaha
