Question

s. The s-t graphs of two moving particles subtend
the angles 60 and 30° respectively with the time
axis. What is the ratio of their Velocities, compare
their accelerations in the (vt) graph,​

Answer 1

Answer:

3:1

Explanation:

Velocity is given by the slope of s-t graph

let the velocities be v1 and v2

We know that slope is given by tan(theta)   [where theta is angle made with positive x axis]

=> v1=tan60=root3

=>v2=tan30=1/root3

v1:v2= root3 : 1/root3

         =3:1

Since velocities are constant, a=0

Hope it helps!!!
