Step 1
Given, diameter wheel =56.0cm,
Debble makes three sands in a second.
Step 2
(a) Here time period of pebble =13sec
Since T=2πRVV=2πRT2π(0.562)(3)
V=3π(0.56)=5.98ms=5.28ms
(b) Acceleration of pebble, ac=V2R=(5.28)2(0.28)=99.56ms2

If the pebble by 3 times per sec, then the angular speed is given in xidian is 3secs×2π=18.84rads
a) Tangontial speed is found with is
V=rω
=(0.562)8.84
=5.27ms
b) Acceleration is
a=v2r
=(5.27)2(0.562)
=99.18ms2
