a dog sits 1.34m from the center of a merrygo round with an angular speed of 1.26rad/s. if the magnitude of the force that maintains the dog's circular motion is 43.8N, what is the dog's mass? answer in units of kg?

1 answer

Solve

M R w^2 = 53.8 N, for M

M = 43.8/(R w^2)

w is the angular speed, 1.26 rad/s
R = 1.34 m
