A carpenter constructs a block letter ""L"" using 10 square ceramic tiles. The letter is 7 tiles high and 4 tiles wide as shown in the figure. Find the center of mass of this item relative to the lower left corner O. Express your result in the units of the tile width d =1.

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a

Ameter stick is pivoted at the 0.50-m line. a 3.0-kg object is hung from the 0.15-m line. where should a 5.0-kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
