The first thing that I did was calculate the momentume of each shape before the collisions. To find the momentum
before the collision I used thew equation p=m*v. Using
this equation I found the momentums for the triangle and
the circle. For the triangle the before momentum
was(2kg)*(4m/s) = 8kg*m/s and the circle was (6kg)*(4m/
s) =24kg*m/s. With those two shapes coliding I had to add
both of those numbers together and it would be 32kg*m/s.
Next, I used the momentum equation (p=m*v) to figure out
who's speed was found AFTER the collision which was
(32-24)= 8kg*m/s. Since the momentum before was
32kg*m/s. I subtracted the total by the circle before and
the circle after thr collision. Finally I usesd the
momentum equation, solved for v (p=m*--> v=p/m) to
determine the velocity of the circle after the collision

-I want this re-worded but similar

Write the function getkthdigit(n, k) that takes a possibly-negative int n and a non-negative int k, and returns the kth digit of n, starting from 0, counting from the right

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit

What’s #16 asking and how do i solve it?
