**Math-II ( Joint and Combined Variation)**

1. R=KST, so K = R/ST = (1/6)/[(1/8)(3)] = 4/9 R = 4/9 ST = (4/9)(2)(11) = 88/9 2. U=KLH/S, so K = US/LH = (1.8)(-7.2)/[(6.4)(1.5)] = -1.35 U = -1.35(4.3)(5.1)/-2.2 = 13.457

**Math**

combined rate = 1/4 + 1/6 + 1/2 = 11/12 so time taken for working at combined rate = 1/(11/12) = 12/11 hours or 1 hour and about 5 minutes

**math**

julie's rate = 1/4 pat's rate = 1/+ combined rate = 1/4+1/6 = 5/12 time at combined rate = 1/(5/12) = 12/5 12/5 = 2 hours and 24 minutes take it from there

**Dynamics**

Assuming 1.4m/s^2 is the combined radial acceleration (ar) and tangential (at). Note that the two accelerations are orthogonal (perpendicular) so that the combined acceleration can be found using Pythagoras theorem. ar=v²/r=v²/45 at=1.2 where v=tangential velocity ...
