● 45. A spring of unstretched length L and spring constant k is attached to a wall and an object of mass M resting on a fric- tionless surface (Figure 12-24). The object is pulled such that the spring is stretched a distance A then released. Let the +x direc- tion be to the right. (a) What is the position function x(t) for the object? Take x = 0 to be the position of the object when the spring is relaxed. (b) What is the velocity of the object at t = (7/6)T, where T is the period? (c) What is the acceleration of the object at t = T/4? Example 12-3 olgmis gnol Sumqa k +A Slavol L- 18 borbe Figure 12-24 Problem 45 M broq mort ● 45.
