Two particles have positions at time t given by s1=4t-t^2 and s2=5t^2-t^3. Find the velocities

Step-by-step explanation:

Given that,

The positions of the first particle,

Velocity,

Position,

Hence, this is the required solution.

f

step-by-step explanation:

f

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
