A block weighing 2 kg is suspended from a hook in the ceiling of a truck trailer by a hanging bungee cord. The cord has a cross-sectional area 45 mm and an unstretched length of 38 cm. Part 1: Before Acceleration The truck begins stopped at a red light on a state highway. While stopped, the block hangs straight down to a distance 43 cm below the hook that attaches the bungee cord to the ceiling of the truck (ə) What is the spring constant of the cord? k = 392 Nim II. During Acceleration After the light turns green, the track begins to accelerate. As it does, the spring stretches to a length 53 cm. (b) What is the magnitude of the force on the block? T58. The bungen cord utratches at an angle (the stretching is in the same direction at the cord, toit). The uratching can be broken down into components, horlzontal and vertical based on the forces applied. (c) How much does the cord stretch in the 2-direction? 4) What is the direction of the conform the block to the hook? 19.02% X 1) What is the acceleration of the truck in order to suspend the block in the direction 20:42 X (9) What is the position of the block with the hook as the origin i. - Oom X 9.496 cm III.
