Question

Friends please find the speed of above question.​

Answer 1

Answer:

Slope of this graph describe velocity

Given dx= 20 cm, dt= 0.15 sec.

Or dx= 20/100m , dt = 15/100 sec.

Now, dv will be dx/dt

or dv = 20/100x 100/15 = 20/15 m/s

or dv = 1.3 m/s

Answer 2

Answer

Slope of this graph describe velocity

Given dx= 20 cm, dt= 0.15 sec.

Or dx= 20/100m , dt = 15/100 sec.

Now, dv will be dx/dt

or dv = 20/100x 100/15 = 20/15 m/s

or dv = 1.3 m/s
