A 110kg box is pushed across a surface with a kinetic mu of 0.060. The box accelerates at 0.4m/s. What force was used?

What are the three ways that an object can accelerate

Which accurately compares concave and convex lenses?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
