Question

draw velocity time graph from the given displacement time graph in above question no 15​

Answer 1

The displacement-time graph presents the variation of position of the object with time. the slope of the graph is the instantaneous velocity at that moment.

Answer 2

Velocity from 0 to 50 secs  =  2 m/s  , Velocity from 50 to 100 secs  = -2 m/s

Step-by-step explanation:

Velocity =  Change in Displacement  / Change in Time

From 0 to 50 Sec

Displacement is increasing uniformly  

Velocity from 0 to 50 secs  =  ( 100 - 0)/(50 - 0)  = 2 m/s

From 50 to 100 Sec

Displacement is Decreasing uniformly  

Velocity from 50 to 100 secs  =  (0 - 100)(100- 50)  = - 2 m/s

Velocity from 0 to 50 secs  =  2 m/s

Velocity from 50 to 100 secs  = -2 m/s
