A stone of mass 0.6kg attached to a string of length 0.5m is whirled in a horizontal circle at a constant
speed. If the maximum tension in the string is 5N before it breaks, calculate:
a) The maximum speed of the stone
b) The maximum number of revolutions per second it can make

Answers


Moraa
a) The maximum speed of the stone
V=(r FC/m)1/2 =(0.5*5/0.6)1/2 = 5m/s.
b) The maximum number of revolutions per second it can make
f=?/2p =v/2pr
= 5/2p*0.5 =1.593Hz.
