got it. i was trying to do an indefinite integral and then plug in t, silly me, it was late last night haha.

one more thing. i got that, and i got part b, which asked for the time at which the speed is .75vt i'm now stuck on part c, which says: (c)How far has the object traveled in the first 5.93 s of motion? I realize i need to integrate somehow, but I'm not sure exactly what to do...

ok, so: v = mg/b(1-e^(-bt/m))=mg/(2b) mg/b's cancel, so 1-e^(-5.93b/m)=.5 .5=e^-5.93b/9 9ln.5=-5.93b -6.2383=-5.93b b=1.052 vt = 88.2/b = 88.2/1.052=83.8403 and...i got it. for some reason i was pluggin in 5.5 not 5.93, thanks for letting me know i was doing it right.

Homework Statement A 9.00 kg object starting from rest falls through a viscous medium and experiences a resistive force R = -bv, where v is the velocity of the object. If the object reaches one-half its terminal speed in 5.93 s, (a) determine the terminal speed. Homework Equations...

no, up is not towards the center of rotation. it is 36.1 degrees past the bottom

Homework Statement A ball swings in a vertical circle at the end of a rope 1.30 m long. When the ball is 36.1° past the lowest point on its way up, its total acceleration is (-22.5 i + 20.2 j) m/s2. (a) Determine the magnitude of its radial acceleration. (b) Determine the speed and velocity...
