Step 1

Given, diameter wheel$=56.0cm$ ,

Debble makes three sands in a second.

Step 2

(a) Here time period of pebble$=\frac{1}{3}\mathrm{sec}$

Since$T=\frac{2\pi R}{V}\Rightarrow V=\frac{2\pi R}{T}\Rightarrow 2\pi \left(\frac{0.56}{2}\right)\left(3\right)$

$V=3\pi \left(0.56\right)=5.98\frac{m}{s}=5.28\frac{m}{s}$

(b) Acceleration of pebble,$a}_{c}=\frac{{V}^{2}}{R}=\frac{{\left(5.28\right)}^{2}}{\left(0.28\right)}=99.56\frac{m}{{s}^{2}$

If the pebble by 3 times per sec, then the angular speed is given in xidian is $3\frac{\mathrm{sec}}{s}\times 2\pi =18.84ra\frac{d}{s}$

a) Tangontial speed is found with is

$V=r\omega$

$=\left(\frac{0.56}{2}\right)\cdot 8.84$

$=5.27\frac{m}{s}$

b) Acceleration is

$a=\frac{{v}^{2}}{r}$

$=\frac{{\left(5.27\right)}^{2}}{\left(\frac{0.56}{2}\right)}$

$=99.18\frac{m}{{s}^{2}}$

a) Tangontial speed is found with is

b) Acceleration is
