1.A solid cylinder rolls without slipping down a 30° slope.
Find the minimum coefficient of friction needed to prevent
slipping.
2.A rectangular block 0.25m wide and 0.5m height is dragged to the
right along a level surface at constant speed by a horizontal force
P (acting on the right side of the block with height h above the
level surface) Find the value of h at which the block just starts
to tip (a) 0.4375m (b) 0.3125m (c) 0.1375m (d)...

3. For experiment A, use equations 1&3 to develop a general equation for the value of tension (T) based on the values of the two masses. You will need this later to answer lab question (4), so write it in now. 4. Based on the "net force" and "total mass" approach that was used to derive equations 3,4, and 5; develop the equation for acceleration of two masses (m, and m2) hanging vertically from either side of a frictionless pulley....

In your view,is the kind of child slavery discussed in
this case absolutely wrong no matter what,or is it only relatively
wrong,ie.,if one
happens to live in a society(like ours) that disapproves of child
slavery? Explain your view and why you hold it.
