s odott gi Page 204 Practice Problem 7.10: 53 - O-TOUS Find the skateboard's speed at the bottom of the pipe if he is given a push at the top edge, so that he has an initial downward speed of 2.00 m/s. Answer: 7.93 m/s. EXAMPLE 7.10 Calculating speed along a vertical circle Here we will tackle a circular-motion problem using conservation of energy. Because the acceleration in this problem is not constant, we cannot approach it with the tools...

Page 205 Practice Problem 7.12: If the 0.610 N force is removed when the glider reaches the O. is removed when the glider reaches the 0.10 m point, at what distance from the starting point does the glider come to rest? Answer: EXAMPLE 7.12 Work and energy on an air track DH Video Tutor Solution Now let's revisit Example 7.8, adding a nonconservative force to the system. Suppose the glider is initially at rest at x = 0, with the...

Q16. Consider the box in the drawing. We can slide the box up the frictionless incline from point A and to point Cor we can slide it along the frictionless horizontal surface from point to point Band then lift it to point How does the work done on the box along path A-c to the work done on the box along the two step path A greater...
