Normally, one would think that an object generating large amounts of thrust would fly all over the place with no clear direction. How does a rocket stabilize and launch perfectly straight up?

But the questions asks "Calculate the magnitude of force a backpacker must exert", which is the sum of the two tensions forces. So wouldn't my answer be correct?

(a) (3.8m)2 + (1.5m)2 = x2 x = 4.085m Fg = Ftsin\theta (16kg)(9.8 m/s2) = Ft(1.5/4.085) F = 427N Correct?

Homework Statement Two trees are 7.6m apart. Calculate the magnitude of force a backpacker must exert to hold a 16-kg backpack so that the rope sags at its midpoint by (a) 1.5m, (b) 0.15m. http://2.bp.blogspot.com/_qDvB7jRAneY/SrLIlGBVq1I/AAAAAAAAAVA/J8UdxspkfSk/s1600-h/bear+sling.bmp"...
