A cookie jar is moving up a $\backslash (42^\{\backslash$circ$\}\backslash )$ incline. At a point $60$ cm from the bottom of the incline $($measured along the incline$),$ the jar has a speed of $\backslash (1\mathrm{.}4\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ The coefficient of kinetic friction between jar and incline is $0\mathrm{.}17.($a$)$ How much farther up the incline will the jar move? $($b$)$ How fast will it be going when it has slid back to the bottom of the incline? $($c$)$ Do the answers to $($a$)$ and $($b$)$ increase, decrease, or remain the same if we decrease the coefficient of kinetic friction $($but do not change the given speed or location$)?$
