Kayla, a fitness trainer, develops a new exercise. The exerciseinvolves using a rope to pull a crate of mass M = 45.0 kgalong a carpeted track. Using her physics expertise, Kayladetermines that the coefficients of kinetic and static frictionbetween the crate and the carpet are µ = 0.430 andμs = 0.770, respectively.Kayla uses one of her employees, Ramon, to test the exercise.Use g = 9.80 m/s² for the gravitational acceleration.If the rope makes an angle of 0 = 29.0° with the floor, whatis the minimum force Fmin that Ramon must apply to set thecrate in motion?Next, Kayla has Ramon pull on the rope as hard as he can. Ifhe pulls with a force of F = 295 N along the direction of therope, and the rope makes the same angle of 0 = 29.0° withthe floor, what is the acceleration a of the box?Fmina ==MFNm/s²
