Question

A lubricating oil is driven through a pipe using an electric pump. The speed of an oil particle is plotted in the first 10 s of operation. Determine the acceleration of an oil particle through every stage shown on the graph.

Velocity-time graph showing three stages of oil particle acceleration over 10 seconds.

Accepted Answer

First stage a = 3.5 m/s² ;
Second stage a = - 0.6 m/s² ;
Third stage a = 0 m/s²

Answer

First stage a = 3.5 m/s² ;
Second stage a = 0.6 m/s² ;
Third stage a = 4.0 m/s²

Answer

First stage a = - 3.5 m/s² ;
Second stage a = 0.6 m/s² ;
Third stage a = - 4.0 m/s²

Answer

First stage a = - 3.5 m/s² ;
Second stage a = 0.6 m/s² ;
Third stage a = 0 m/s²
