1. Microtubules are intracellular protein molecules that help cells hold their shape. In addition, microtubules are responsible for various kinds of movements within cells, such as pulling apart chromosomes during cell division. Microtubules are assembled from small, identical subunits and can exert forces measured to be from a few piconewtons up to hundreds of nanonewtons. The bacterium Escherichia coli contains a chromosome that has a mass equal to about 10-17 kg. If a microtubule applies a force of 1 pN to the chromosome, what would the magnitude of its acceleration be in the absence of any other force?

2.The space shuttle takes off vertically from rest with an acceleration of 29 m/s2 . What force is exerted on a 75 kg astronaut during takeoff? Express your answer in newtons and also multiples of the astronaut

Explanation / Answer

apply force F = ma in each case

so

#1 :

accleration a     = F/m

a = 1e-12/1e-17

a = 1*10^5 m/s^2

----------------------------------

2. F = ma

F = 75*29

F = 2175 N

------------------------------

appply T - ma = mg

a = (T-mg)/m

at highest point , V is zero and a = -g
