Force of kinesin molecule within cells

AI Thread Summary
Kinesin molecules transport organelles along microtubules within cells, requiring a specific force to accelerate them. The problem involves calculating the force needed to accelerate an organelle with a mass of 0.028 picograms from rest to a velocity of 2.8 micrometers per second in 45 microseconds. The initial attempt at the solution involved converting units but resulted in an incorrect answer. The discussion indicates that while the conversions were correct, there may have been a miscalculation in the final force determination. Accurate calculations are essential for understanding the dynamics of kinesin transport.

Homework Statement

Within cells, small organelles containing newly synthesized proteins are transported along microtubules by tiny molecular motors called kinesins. What force does a kinesin molecule need to deliver in order to accelerate an organelle having mass 0.028 pg from rest to 2.8 microm/s over a time of 45.0 micros?

The Attempt at a Solution

i converted the micro to m and s, 2.8x10^-6 m/s and 2.8x10^-17 kg and 4.5x10^-5 s. for my answer i got 1.87x10^-18m/s but its wrong...thanks for help!

The conversions look OK. I suppose you made a mistake in your calculations.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
