1.
A 17-kg box moves along the x axis under the influence of a variable force. The potential energy is given by U(x) = 6 x + 7 x ; where x is in coordinate of the particle. The unit of potential energy is Joule (J) and the unit of x is meter (m). If the box has a speed of 16 m/s when it is at x1 = 2.0 m, what is its speed when it is at x2 = 3.0 m? Please round your answer to one decimal place.A 21-kg block is released from rest at hy = 35 m above the ground. What is its speed, v2 in m/s, when it is h2 = 6 m above the ground? Take the acceleration due to gravity, g, as 9.80 m/s . Please round your answer to one decimal placeStep by Step Solution
