Help please 30 points! What is the angular speed and the tangential velocity at the edge of a disk with a radius of 12.5 cm if it
completes 10 revolutions in 4.18 s?

(Show work)

double the distance = divide strength by 4

in physics zero. in muscle fatigue could be high

it has to be b, about 97 percent.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
