A particle moves so that r(t) = ati + b sin atj. Show that the magnitude of the acceleration of the particle is proportional to its distance from the x-axis.

Step-by-step explanation:

Given

Position of particle is

i.e. distance from x axis is

Distance from y axis at

velocity is given by

Similarly acceleration is given by

Magnitude of acceleration is

From 1 and 2 we can see that

Magnitude of acceleration is proportional to distance from x axis

answer: it is 1: 47 pm

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
