When Santa arrived in Texas on Christmas eve, it was cold and snowy and the roofs were very icy. Santa landed his sleigh and stepped out onto the icy roof. As Santa's foot pushed backward, an equal
and opposite force pushed the sleigh forward on the icy surface. Luckily, Rudolph and Dancer kept
the sleigh from sliding off the roof!

Is this the Law of Inertia (1st), Law of Acceleration (2nd) or Law of Action/Reaction (3rd)?

Explain
your reasoning.

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^.
