Show that the radial acceleration is zero when 60 = rad
Transcribed Image Text:Show that the radial acceleration is zero when 60 = rad
Hints: a) The trajectory is given, so to sketch velocity and acceleration vectors at three different points find the velocity and acceleration (for acceleration a see hints given in part b). v = ř f + rê ð and a = (* – rở ) î + (rë + 2řė) ôð The components of velocity and acceleration in polar coordinates should give a feeling about magnitude and direction of vectors v and a as function of position. You do not need to be perfect in the sketch , just give e feeling (i.e., do not calculate) how the magnitude and direction of these vectors change as function of position . Remember velocity is always in the tangential direction with the trajectory, which in our case is a spiral one and not a circular one from the formula of the acceleration in polar coordinates prove that 5a²f² b) a = (* – ri) î + (rë + 2řė) ôð = (¤ 2л 2л 5a?f ) ê + 2л () (1 – 20) F + 50 ê] a=( 2л
