1. A simple pendulum is suspended from the ceiling by means of a string of length 1.14 m. Assume that there is no friction or air resistance. Suppose you were to release the pendulum from rest, starting from an angle of 58.2 degrees with respect to the vertical, as shown. What will be the speed of the pendulum at the instant it swings through its lowest point (that is, when it s momentarily hanging vertically)? 2.28 m/s 3.25 m/s 3.43 m/s 4.73 m/s
2. A 10.0-kg block is released from rest at a rough 5.0 m long 30° incline. The coefficient of kinetic friction between incline and box is 0.2.

Problem 4: A child's toy consists of a m = 35 g monkey suspended from a spring of negligible mass and spring constant k. When the toy monkey is first hung on the spring and the system reaches equilibrium, the spring has stretched a distance of x = 11.1 cm, as shown in the diagram. This toy is so adorable you pull the monkey down an additional d = 4.7 cm from equilibrium and release it from rest, and smile with delight as it bounces playfully up and down.
