Question

please solve this I will mark you brainliest ​

Answer 1

hey mate !!

Answer:

as we know

velocity = displacement/time

therefore

a) 3/2

b)3/5

c) 3/3=1

Explanation:

i would have explained it more clearly if it would have been of at leat 10 to 15 points.

hope u understand !!

Answer 2

We are asked to find out the velocity!

(a) From section A to B

$:\implies \sf Velocity \: = \dfrac{Displacement}{Time} \\ \\ :\implies \sf Velocity \: = \dfrac{3}{2} \\ \\ :\implies \sf Velocity \: = 1.5 \: ms^{-1} \\ \\ {\pmb{\sf{Henceforth, \: solved!}}}$

(b) From section B to C

$:\implies \sf Velocity \: = \dfrac{Displacement}{Time} \\ \\ :\implies \sf Velocity \: = \dfrac{3}{(7-2)} \\ \\ :\implies \sf Velocity \: = \dfrac{3}{5} \\ \\ :\implies \sf Velocity \: = 0.6 \: ms^{-1} \\ \\ {\pmb{\sf{Henceforth, \: solved!}}}$

(c) From C to D

$:\implies \sf Velocity \: = \dfrac{Displacement}{Time} \\ \\ :\implies \sf Velocity \: = \dfrac{3}{(10-7)} \\ \\ :\implies \sf Velocity \: = \dfrac{3}{3} \\ \\ :\implies \sf Velocity \: = 1 \: ms^{-1} \\ \\ {\pmb{\sf{Henceforth, \: solved!}}}$

Additional information:

→ In a velocity time graph, the slope of graph tell us about the acceleration. If the slope is high then the acceleration is positive, if the solve is low then the acceleration is negative and if the slope is parallel to time axis then there is no acceleration taking place!

→ In a velocity time graph if we have to find out the distance or displacement then we have to find out the area under the curve!
