(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
The Green Monster, as shown below, is a wall 37 feet high in left field at Fenway Park in Boston. The wall is 310 feet from home plate down the third base line. If the batter hits the ball 4 feet above the ground, neglecting air resistance, determine the minimum speed that the bat must impart to the ball that is hit over the Green Monster. COVIDIE CVS. ELABOR The equations of motions for the baseball are x(t) = (u...
Help with Data Science python notebook, Question 1 Create a function called vowel_parse() that takes a single string as input. This string is the name of the input directory. It returns a dictionary. This dictionary has keys that are the names of the individual input files. The dictionary values are the number of words in that file that have adjacent vowels ('aa', 'ae', 'oo', 'ia', etc.). Use a regular expression to find these, do not hard code every possible combination...
