Question

I Displacement - time graph of the objects a and b are shown .compare their velocities
help me guyzz
​

Answer 1

Answer:

velocity of B>A

Explanation:

in a displacement time graph slope of the line gives us the value of velocity.

slope = (change in y coordinate)/change in corresponding x coordinate)

         =change in displacement/time interval

         = velocity.

slope of line = tan(x) where x = angle made subtended at x axis.

for A: velocity=slope = tan45 =1  

for B: velocity=slope=tan60= root 3

as 1 < root 3  

so, velocity of B>A
