1. The problem statement, all variables and given/known data What is the magnitude of the acceleration of a speck of clay on the edge of a potter's wheel turning at 40 rpm (revolutions per minute) if the wheel's diameter is 35 cm? 2. Relevant equations v=2(pi)(r)/t a=(v^2)/r 3. The attempt at a solution 2(3.14)(.175)/.67 = 1.099 (1.099^2)/.175=a
Welcome to PF. Isn't your period 1.5 instead of .67? You only get 40 revs per min so a rev should be longer than a sec no?
