Ms A truck covers 370 m in 860 s while smoothly slowing down to final speed of 260 ms a Find its original speed ms b Find its acceleration. Acceleration is change in velocity speed andor direction over an interval of time. V avg average velocity ms v i the initial velocity ms.
As a quick example lets say a train accelerates at a constant rate from 30 ms to 80 ms.
Another equation for the average velocity is. Average velocity velocity₁ time₁ velocity₂ time₂. Ms A truck covers 370 m in 860 s while smoothly slowing down to final speed of 260 ms a Find its original speed ms b Find its acceleration. V avg average velocity ms v i the initial velocity ms.
