A 5.0 kg rock is attached to a rope that is 1.0 meters in length. The other end of the rope is attached to a
motor that forces the rope to rotate with a rotational
speed of 4.0 rad/s. Calculate the magnitude of the
centripetal force acting on the rock.

co2reflects heat radiation back to earth buning coal and oil emits co2 globe warms

frequency or wavelenth of em radiation in a vacuum

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
