Question

A 0.7 kg flying pig travels in a circle hanging from a 20 m cord that makes an 11 degree angle with the vertical. What is the flying pigs tangential velocity?

Answer 1

Given is:-

Mass of the pig m = 0.7 kg

Length of the cord L = 20 m

Angle  

II = 0

now,

using Newton's second law of motion, we get

eq-1

mv2 Tsint =

and

eq-2

T cost = mg

by dividing eq-1 by eq-2 we get

tand = a rg

or

tan = (Lsing

by plugging all the values we get

tan(11°) = 7 (20m (sin(11°))) (9.8m/s2)

which gives us

v = 2.69621m/s

This is the tangential velocity of the flying pig.
