Physics Part 2
Rick's next shot isn't as good. She hits the cue ball with a velocity of 5.6 m/s and it hits the 4 ball. The cue ball bounces off at a 45 degree angle off it's original path at a speed of 3.5 m/s. What is the velocity of the 4 ball? ---So all i know is the momentum...

Okay, so i did my math wrong sorry and thx Steve!! and bobpursley, does that mean the cue ball is traveling .27 m/s straight?? because usually they want angle but since it's head on it's just straight rite?

Rick is playing billiards and hits the cue ball. It makes contact with the 8 ball head on. If before the collision the cue ball was travelling at 2.4 m/s and after the collision the 8 ball was traveling at 2.13 m/s. How fast and in what direction is the cue ball traveling? (Ma...
Three solutions are mixed together to form a single solution. One contains 0.2 mol \rm mol Pb(CH 3 COO) 2 \rm Pb(CH_3COO)_2, the second contains 0.1 mol \rm mol Na 2 S \rm Na_2S, and the third contains 0.1 mol \rm mol CaCl 2 \rm CaCl_2. Write the precipitation reaction.
Problem 2 the answer is 4.5% You now the correct answer for the problem 7?
this test is easy listen the videos and do the exercises of those videos and it's easy. If you have any doubt just ask.
Mean=300*0.5=150 SD=SQRT(300*0.5*(1-0.5))=8.66 Z=+/- (170.5-150)/8.66 = +/- 2.37 Table of Z P= 2*0.0089 = 1.78% +/- because we have two-tailed and multiple the value of P by 2 for the same reason
thanks :) had achieved good luck to the course excuse the English'm from Portugal
you know the correct answer to the problem 2 and 6 of the test? The P-value (problem 8) is 1.78 (it is correct)
