Answer:
12 inches, I hope this is right! :)
Step-by-step explanation:
circumference = 75 inches
75 / 2 = 35.7
37.5 / π = 11.9366207
Rounded to the nearest inch:
12 inches
I created this using a graphing calculator website called Desmos! You can use this to further explore slopes and lines and graphing in general :)
Use the kinematics equation:
v1^2-v0^2=2as
since v1=0 (at height of 81 ft), and a=g=-32.2, substitute values:
0-v0^2=2*(-32.2)(81 ft)
Solve for v0
v0=sqrt(2*32.2*81)=72.2 m/s
