Grain Sack
Questions about energy?
I really need help on this topic. Everyone says it's easy … but I do not understand. I have some questions I feel cover the areas where I am lost. Please explain how to find questions and answers. Also, if you wish, please resolve them. 1. A N 9.80 bag of grain is hoisted to a storage room of 50.0 m above the floor of a grain elevator. How much work has been done? What is the increase in potential energy of the sack of grain at this stage? 2. An archer puts a 0.30 kg of arrow on the bowstring. An average force of 201 N is exerted to draw the text string 1.3 m Assuming that all the energy that goes into the arrow, how fast the arrow left the bow? If the arrow is shot upward how hich Does it rise? Thank you, "asian_al
The work done in the first case is the following. W = 9.8 N * m = 50 joules. The increase in potential energy is the same. The second case: Then the work done = force * distance is: W = F * d = 201 N * 1.3 m and the final kinetic energy is Ek = 1 / 2 * m * V ^ 2 solving for V = sqrt (Ek * 2 / m) Height maxim is: H = V ^ 2 / (2 * g) where g = 9.8 m / sec ^ 2 the acceleration of gravity, is to make the calculations. Good luck.
