Question

It takes 5.0 seconds to complete one revolution when the radius of the circle is 50.cm. In this case, what is the angle, θ, that the string makes to the vertical? Give your answer in degrees, without units and correct to two significant figures. Take acceleration due to gravity, g, as 9.81 m s-2.

Answer 1

Answer:

To compare this with the acceleration due to gravity (g = 9.80 m/s2), we take the ratio of acg=(1.25 m/s2)(9.80 m/s2)= 0.128 ..
