Answer:
A child's toy consists of a piece of plastic attached to a spring in the figure below. The spring is compressed against the floor a distance of 2.00 cm, and the toy is released. If the toy has a mass of 117 g and rises to a maximum height of 45.0 cm, estimate the force constant of the spring.
Step-by-step explanation:
Answer:
216.7
Step-by-step explanation:
Use the Law of Sine Formula:
a/SinA = b/SinB = c/SinC
You are looking for side "b" in this case
Add up the Angles first so you can get Angle C:
180 - (80+70) = 30
After you get that, you have all your needed information to find "b":
b/Sin80 = 110/Sin30
Cross multiply and you will get:
b . Sin30 = 110 . Sin80
b = (110 . Sin80)/Sin30
Enter that into your calculator and you will get "216.7"
