20. A ball of mass 5.0 kg is tied to the end of a 75-cm length of string. The ball and string are swung in a circle in a vertical plane at constant speed y, which is the minimum speed necessary to keep the string taut at all times. The center of the circle is a distance h = 190 cm above the floor.
Suddenly, the string is released at the instant the ball is at point , located half way from the top to the bottom on the ascending arc. After what span of time does the ball hit the floor?
75 cm

As newton's first law states a object in motion stays in motion

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
