Part A

A small sphere of radius $r_0=1\mathrm{.}5cm$ rolls without slipping

on the track shown in the figure whose radius is $R_0=$

$24\mathrm{.}0cm.$ The sphere starts rolling at a height $R_0$ above

the bottom of the track. $($Figure $1)$

When it leaves the track after passing through an angle of $135$ as shown, what will be its speed.

Express your answer using two significant figures.

$v=$

$\frac{m}{s}$

Incorrect; Try Again; One attempt remaining

Part B

When it leaves the track after passing through an angle of $135$ as shown, at what distance $D$ from the base of the track will the sphere hit the ground?

Express your answer using two significant figures.

$D=$

$m$
