Question 1147700: A 2kg body is tied to the end of a chord and whirled in a horizontal circle of radius 1.5m at 3 revolutions per sec. Neglecting the attraction due to gravity, find the acceleration of the body toward the center of the circle is m/s2? Answer by ikleyn(52848) (Show Source):
The circular linear velocity of the mass is v = = 2*3.14*1.5*3 = 28.26 m/s.
The acceleration of the body toward the center of the circle is
a = .
Substitute the found value of "v" and the given value of "R" into the formula and calculate.
By the way, the mass value is IRRELEVANT in this problem (!)
