A man pushes a 350-lb box across the floor. The coefficient of kinetic friction between the floor and the box is = 0.17 at an angle a 12 what is the magnitude of the force he must exert to slide the box across the floor? in lbs 61.12 O 63.11
If the angle a=25°, what tension in newton must the man exerts on the rope to move the crate at constant speed? If x=0.25 and the mass of the crate is 50 kg. O 168.56 20027 10"
