Question

Your cousin's baby carrier has a toy hanging vertically on a spring from the top of the carrier, when you start at t = 0 by releasing the toy from being pulled down 10cm, it bobs up and down 2 cycles every second. Plot the y-position of the toy vs. time below, showing at least two complete cycles of oscillations. Use positive y- direction as upwards and negative y-direction as downwards. Draw your graph, take a picture, and upload it into your pre-lab document. With this plot, answer the following: If you pull down the toy 20cm instead of 10cm, what part of your plot changes, and how? 1. If you hook a weight on to the baby toy, and again pull down the combined mass system 10cm, what part of your plot changes, and how? Be prepared to discuss at the start of lab how the velocity and acceleration graphs look. 2. 3.

Plots:

1) When toy is pulled down by 10cm:

10 0 0.5 1.5 2 -10

2) When toy is pulled down by 20cm:

dlown 20 0 2 4 20

Note: no of cycles is the same as in last plot, it's zoomed out to show full plot(vertical part).

3) When mass is increased:
