same xxxxxx and xxxxx hitting xxx wall xxx direction xx motion xxxxxxxx meaning xxx velocity xxx changed xxxxx includes xxxx peed xxx direction x ball xxxx to x string xxxxxxxx at xxx other xxx to x rigid xxxxxxx forms x pendulum xx we xxxx the xxxx to xxx side xxx release xx the xxxx moves xxxx and xxxxx along xx arc xxxxxxxxxx by xxx string xxxxxx a xx the xxxxxxxx constant xx this xxxxxxx Explain x Is xxx speed xxxxxx to xx constant xx this xxxxxxx What xxxxxxx to xxx speed xxxx the xxxx reverses xxxxxxxxx Ans xxxxxxxxx to xx understanding xxx pendulum's xxxxxxxx it xxxxxxxx since xxx speed xx subjected xx variations xx turn xxx direction xx the xxxxxxxx is xxxxxxxxxx changing xx relation xx pendulum xxxxxx back xxxxxxx point xx add xxxxx that xxxxxxxx being x vector xxxxxxxx depends xx both xxxxx and xxxxxxxxx Secondly xxxxxxxx I xxxxx about xxxxx being xxxxxxxx it xx not x rule xxxxxxx speed x when xx research xxx bottom xx the xxxxx and xxxxxxxxx to xxxx at xxx highest xxxxx because xx the xxxxxxxxx between xxxxxxx and xxxxxxxxx energy xxxx at xxx highest xxxxx the xxxxxxxx has xxxxxxx potential xxxxxx which xx converted xx kinetic xxxxxx as xx swings xxxxxxxx A xxxxxx of x car xxxxx on xxx brakes xxxxxxx the xxxxxxxx of xxx car xx decrease xxxxxxxxx to xxx definition xx acceleration xxxxxxxx in xxxx chapter xxxx the xxx accelerate xx this xxxxxxx Explain xxx Since xxx car xx decelerating xxx to xxxxxxx it xx accelerating xxxxx can xx defined xx the xxxx of xxxxxx of xxxxxxxx but xxxx if xxx car's xxxxx is xxxxxxxxxx eventually xxx velocity xx changing xx direction xxx to xxx deceleration x car xxxx starting xx from x stop xxxx has xxxx velocity xx the xxxxxxx it xxxxxx Must xxx acceleration xx the xxx also xx zero xx this xxxxxxx Explain xxx According xx my xxxxxxxxxxxxx the xxxxxxxxxxxx of x car xxxxxxxx from xxxx is xxx zero xx that xxxxxxx because xxx car xxx zero xxxxxxxx its xxxxxxxx is xxxxxxxx from xxxx to x non-zero xxxxx meaning xx is

xx the xxx Which xx these xxx objects xx likely xx have xxx larger xxxxxxxxxxxx at xxxx instant xxxxxxx Ans xxx racing xxxxxx car xx likely xx have xxx larger xxxxxxxxxxxx at xxxx instant xxxxx the xxxxxx might xxxx be xxxxxxxxxxxx to xxxx out xx the xxx the xxxxx acceleration xxxxx be xxxxxxxxxxxxx greater xxx to xxx much xxxxxx mass xxx the xxxxxxx to xxxxxxx increase xxx velocity xx Question x railroad xxxxxx moves xxxxxxx along x straight xxxxxxx of xxxxx for x distance xx m xxx west xx a xxxxxxxx speed xx m x It xxxx reverses xxx direction xxx travels x due xxxx at x constant xxxxx of x s xxx time xxxxxxxx for xxxx deceleration xxx reversal xx very xxxxx due xx the xxxxx speeds xxxxxxxx a xxxx is xxx time xxxxxxxx for xxx entire xxxxxxx b xxxxxx a xxxxx of xxxxxxx speed xxxxxx time xxx this xxxxxxx Show xxx deceleration xxx reacceleration xxxx reversal xx occurring xxxx a xxxx short xxxx interval x Using xxxxxxxx values xx velocity xx represent xxxxxxxx motion xxxxxx a xxxxx of xxxxxxxx versus xxxx for xxx engine xxx fig x Sketch x graph xx acceleration xxxxxx time xxx the xxxxxx see xxx Ans x Time xxxxxxxx for xxx Entire xxxxxxx First xxx westbound xxxxxxxx m xxxxx m x Time
