You have a 100-watt light bulb on your front porch that is turned on 10 hours every night. If the cost of electricity is 12 cents per KWHR (kilowatt hour), how much does that bulb add to your monthly electric bill? Give your answer in US dollars ($). Remember 100 cents = $1.

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^.
