One of the Mars Rover vehicles, Sojourner, collected red Martian dust on its wheels as it rolled along. There is very little water on Mars, so it's not mud; it's actually dust. Explain, in detail, why the
dust clings to the wheels. Be sure to describe forces by name and mention charging by induction,
conducting, or rubbing, if it is appropriate. Also explain what atoms on Mars must be composed
of.

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?

Astudent pushes on a 20.0 kg box with a force of 50 n at an angle of 30° below the horizontal. the box accelerates at a rate of 0.5 m/s2 across a horizontal floor. what is the value of the normal force on the box? 200 n 243 n 156 n 225 n
