Kayla, a fitness trainer, develops an exercise that involves pulling a heavy crate across a rough surface. The exercise involves using a rope to pull a crate of mass M = 45.0 kg along a carpeted track. Using her physics expertise, Kayla determines that the coefficients of kinetic and static friction between the crate and the carpet are 4 = 0.470 and Hs = 0.810, respectively. Kayla uses one of her employees, Ramon, to test the exercise. If the rope makes an angle of 0 = 25.0° with the floor, what is the minimum force Fmin that Ramon must apply to set the crate in motion? Use g = 9.80 m/s². Next, Kayla has Ramon pull on the rope as hard as he can. If he pulls with a force of F = 305 N along the direction of the rope, and the rope makes the same angle of 0 = 25.0° with the floor, what is the acceleration a of the box? Fmin = a = M F N m/s²
