The spring-mounted 0.62-kg collar A oscillates along the horizontal rod, which is rotating at the constant angular rate ở = 6.3 rad/s. At a certain instant, ris increasing at the rate of 630 mm/s. If the coefficient of kinetic friction between the collar and the rod is 0.46, calculate the friction force Fexerted by the rod on the collar at this instant.

Question
The spring-mounted 0.62-kg collar A oscillates along the horizontal rod, which is rotating at the constant
angular rate ở = 6.3 rad/s. At a certain instant, ris increasing at the rate of 630 mm/s. If the coefficient of
kinetic friction between the collar and the rod is 0.46, calculate the friction force F exerted by the rod on
the collar at this instant.
