- Kayla A Fitness Trainer Develops An Exercise That Involves Pulling A Heavy Crate Across A Rough Surface The Exercise 1 (59.98 KiB) Viewed 53 times
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 μk=0.410 and μs=0.770, respectively. Kayla uses one of her employees, Ramon, to test the exercise. If the rope makes an angle of θ=29:0∘ 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. Fmin= Next, Kayla has Ramon pull on the rope as hard as he can. If he pulls with a force of F=325 N along the direction of the rope, and the rope makes the same angle of θ=29.0∘ with the floor, what is the acceleration a of the box?
