Determine a vector expression for the position of a particle whose velocity is (3t^2 - 8)i + 5j m/s.

r (t) = [integral] v (t) dt = (t^3 - 8t + C) i + (5t + C) j m

Find, using integration, the work done in compressing a spring by a distance x.

[integral from 0 to x']dW= [integral from 0 to x'] F( x') dx' =[integral from 0 to x'] kx' dx' = 1/ 2 k x^2 It is a 1-D problem so line integral do not need to be used. At a given instant, let the amount by ...

Shower-cleaner liquid is sold in spray bottles. The volume of liquid in a bottle may be modelled by a normal distribution with mean 955 ml and a standard deviation of 5 ml. Determine the probability that the volume in a particular bottle is:

a) at most 960 ml Let X be the volume of liquid in a particular bottle, then we want to find P(X <= 960). We first need to transform from X to Z (to the standard normal distribution) so that we can use th...
