Answer:
x22.=L1cosθ1θ1. + L2cosθ2θ2.
y22.=-L1sinθ1.θ1. + L2sinθ2.θ2.
θ1.=θ1.+θ1..dt

Answer:
Angular speed will reach 6.833rad/s before the coin starts slipping
Explanation:
There is no question but I'll asume the common one: Calculate the speed of the turntable before the coin starts slipping.
With a sum of forces:
At this point, friction force is maximum, so:
Solving for V:
V=1.025 m/s
The angular speed of the turntable will be:
ω = V/R = 6.833 rad/s This is the maximum speed it can reach before the coin starts slipping.
All the continents were connected in one large landmass.If you take a map and cut out all the Continent, you can see that they fit together almost perfectly, like a giant puzzle. This idea supports the fact that <span>all the continents were connected in one large landmass.
