Una bola de 2kg se desliza por una superficie sin fricción (ABC) como se muestra en la figura. En A, la energía cinética de la bola es de 10 J y la energía potencial, 54 J. Calcula: a) La altura de la bola en el punto A.
b) La velocidad de la bola en el punto B. c) La velocidad en el punto C.

100 pounds is 100 pounds no matter the object or item being weighed

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.

So since the snail is moving at 3.6  miles per hour you multiply by 5280 to change it into feet per hour. so you get 36*528 ft per hour. since there are 3600 seconds in an hour, you divide 36*528 by 3600. so simplifying we get 528/100 which is 5.28 ft per second
