You are a fitness trainer developing an exercise that involves pulling a heavy crate across a rough surface. You attach a rope to a crate of mass M = 45.0 kg and place it on a carpeted track. The coefficient of kinetic friction between the crate and the carpet is µ = 0.470. To test the apparatus, you have one of your employees pull on the rope as hard as she can. If she pulls with a force F of 315 N along the direction of the rope while the rope makes an angle 0 of 27.0" with the floor, as shown in the figure, what is the acceleration a of the box? r 10 1 m/s² Question Source Freedman Co
A mop is pushed across the floor with a force F of 42.3 Nat an angle of 0 = 50.5%. The mass of the mop head is m= 2.25 kg. Calculate the magnitude of the acceleration a of the mop head if the coefficient of kinetic friction between the mop head and the floor is #4 = 0.325. m/s² DNA Z COLE Question Source
