Because Candy Can't Be Online Today

Hey guys. David here. We all did such a fantastic job with the Math LT. As a reward, we have Physics and Chem homework. T_T :((

PHYSICS – p.109

#55 – (II) A roller coaster reaches the top of the steepest hill with a speed of 6.0 km/h. It then descends the hill, which is at an average angle of 45 degrees and is 45.0m long. What will its speed be when it reaches the bottom? Assume friction coefficient = 0.12.

#56 – (II) An 18.0-kg box is released on a 37.0 degree incline and accelerates down the incline at 0.270 m/s2. Find the friction force impeding its motion. How large is the coefficient of friction?

#60 – (III) The 70-kg climber is supported in the "chimney" by the friction forces exerted on his shoes and back. The static coefficients of friction between his shoes and the wall, and between his back and the wall, are 0.80 and 0.60, respectively. What is the minimum normal force he must exert? Assume the walls are vertical and that friction forces are both at a maximum. (I know, wth)

CHEM

Use Ion-Electron method to balance this equation:
HClO2 --> ClO2+ Cl-

ANNOUNCEMENT:
Meron daw Math LT retake. Dunno when that is though. Details are vague. Will update when I’ve texted Ma’am Kiel.

PAYMENT FOR SHIRTS: Magbayad na bukas dahil Friday gigimmick na ang officers para maghanap ng shirts at printer. Split into teams. The team that finds the cheapest shirt wins points (which of course do not count toward the regular prize).

SATURDAY PRACTICE: Di pa ‘to sure. Pero magtanong-tanong na rin, just in case. We’re pushing for the venue to be Pisay.

Guys, magbayad na kayo sa akin tomorrow or Friday para masaya...
actually para mabili na ung mga shirts and mapaprint before Intrams.


Saturday practice? What're we practicing? The retarded dance thing?


Do the Physics questions have answers at the back? (Hi, someone who has 5th ed. :-")


Math retake is 1:40
