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=2πRV⇒V=2πRT⇒2π(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
