Consider a 2 kg Physics textbook pressed against a wall as shown in the animation. Given that mu_s= .5 and that mu_k = .4 between the wall and the textbook, determine the force that must is on the book perpendicular to the wall. Start
<script language="JavaScript">
function initApplet() {
document.animator.setDefault();
document.animator.shiftPixOrigin(-50,-50);
id=document.animator.addObject("image","file=rarrow.gif");
document.animator.setTrajectory(id,"6","6.4+2.5*t*(-1)");
id=document.animator.addObject("rectangle","x=13.5,y=2,w=10,h=380");
document.animator.setRGB(id,0,0,255);
rid=document.animator.addObject("rectangle","w=40,h=100");
document.animator.setTrajectory(rid,"11","6+2.5*t*(-1)");
document.animator.setRGB(rid,255,0,0);
document.animator.setOneShot(0,8,"End of Animation");
document.animator.forward();
}
