2. Box o' toys. time interval Fchild on b (newtons) 0 to 2 sec. 120 2 sec. to 4 100 sec. 4 sec. to 6 90 sec. Starting at t 0, a child pushes horizontally on a box, making it slide across the floor. Friction exerted by the floor on the box opposes its motion with a force of 100 newtons, and the box has a total mass of 10 kg. The child pushes with a force that changes, as...
A stockroom worker pushes a box with mass 11.9 kg on a horizontal surface with a constant speed of 3.40 m/s . The coefIficient of kinetic friction between the box and the surface is 0.17. What horizontal force must the worker apply to maintain the motion? If the force calculated in the previous part is removed, how far does the box slide before coming to rest?
A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
Please answer and show work for all the questions. (including all Free Body Diagrams). I would appreciate it if you use the original Equations and not the derived ones. updated.. TILL questions 1. Up on the ro up on the rooftop reindeer pause... as they try not to giggle at San and begins to slide - from rest - down the roof. Luckily, there (relative to the diagram below) that helps Santa sio of Fwind. (Once Santa reaches the edge...
