A particle moves so that r(t) = ati + b sin atj. Show that the magnitude of the acceleration of the particle is proportional to
ValentinkaMS [17]

Answer:

Step-by-step explanation:

Given

Position of particle is r(t)=at\hat{i}+b\sin (at)\hat{j}

i.e. distance from x axis is b\sin (at)---1

Distance from y axis at

velocity is given by v=\frac{\mathrm{d} r}{\mathrm{d} t}

v=a\hat{i}+ba\cos (at)\hat{j}

Similarly acceleration is given by

a=\frac{\mathrm{d} v}{\mathrm{d} t}

a=0\hat{i}-a^2b\sin (at)\hat{j}

Magnitude of acceleration is =\sqrt{(-a^2b\sin (at))^2}

=a^2b\sin (at)----2

From 1 and 2 we can see that

Magnitude of acceleration is proportional to distance from x axis

a\propto distance\ from\ x-axis
