Problem 1.37

A point moves along a circle with a velocity v=at,v=a t, where a=0.50 m/s2.a=0.50 \mathrm{~m} / \mathrm{s}^{2} . Find the total acceleration of the point at the moment when it covered the nn -th (n=0.10)(n=0.10) fraction of the circle after the beginning of motion.

Reveal Answer
w=a1+(4πn)2=0.8 m/s2w=a \sqrt{1+(4 \pi n)^{2}}=0.8 \mathrm{~m} / \mathrm{s}^{2}
