How fast would you have to throw a baseball ( m=145 g) to give it the same momentum as a 11 g bullet traveling at 1020 m/s?
You have determined all the torques on the meter stick around point O, and you know all forces except the force that the nail (axis) exerts on the meter stick. Use the condition for translational equilibrium (the vector sum of the forces - 0) to determine this force by finding both the component along the stick and the one perpendicular to the stick. Calculate also the magnitude of this force (square-root of the sum of the squares) and the angle...
How fast should a meter stick be moving in order to appear to be only 60cm?
How fast must a meter stick be moving if its length is observed to shrink to 0.65 m?
Explain how MPI could be used to speed up a sort a million (1,000,000) values. If you have 1000 processors available how fast would your solution be (big O notation). I do not need code for this -- an explanation of an algorithm and how it would work is sufficient.
You are helping a friend move. You throw one of the boxes up at 0.65 m/s and over to your friend at an angle of 32.71 degrees from the back of the truck 0.76 m off the ground. How many seconds, to two decimal places, does it take to hit the ground? Your Answer: Answer Question 4 (1 point) You are carrying an instrument through the jungle to take measurements of air quality in the wild. The instrument can withstand...
How do you define the fast food market? What market structure best describes the fast food industry? Why? Describe briefly what happened in the Fast Food industry until 2012. Which microeconomic/macroeconomic factors played a role? How did McDonald’s react to these influences? Describe the current state of the fast food industry, including macroeconomic indicators, such as unemployment rate, wage rate, etc. How does the fast food industry compare to the overall state of the economy in the U.S.? Which of...
How fast (big O notation is enough) can you check if two lists of n integers each has at least one integer in common? (hint: sorting a list of n integers – meaning putting them in order, takes time with the best algorithms we have). O(nlog(n)
Your toy is stuck on the house roof and to get it down you throw a rock at it. You throw the rock from 2 meters off the ground at 40° above the horizontal. If the toy is 5 meters from the ground and you are 16 meters from the house, how fast will you need to throw the rock in order to hit the toy on the roof?
If you have a number of scores that are outliers you should a) throw them out. b) run the analysis with and without them, to see what difference they make. c) try to identify what is causing those scores to be outliers. d) both b and c
