I am confused on how to find m/s in the following problem: r = 2.6km one revolution of circle = 360s I need it for ac = v^2/r Thanks!, -Mike
Well one rev is always 2pi, so 2pi/360s ... I am unsure of how to convert that. I found one solution that tells me to use C = 2(pi)r and v = d/t, so d = 2(pi)(2600m)... so v = 2(pi)(2600m)/360s .... v = 45.4 m/s? Is this the best way to do the problem or am I making it too complicated?
