Timmy and Andrea wanted to have a fireworks show on July 4h. They lit an assortment of fireworks, watching the fireworks shoot into the air and explode into new and beautiful colors.
What would be two chemical properties of matter of the fireworks? Circle the answer that best
matches your thinking.

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^.
