How Motorcycle Accelerates?

- Aug 02, 2017 -

A motorcycle accelerates from 15 m/s to 20 m/s over a distance of 50 meters. What is its average acceleration?

That depends on the average velocity over the 50 metres. 

average acceleration = change in velocity / time 
time = distance / average velocity 
change in velocity is 5 m/s 
distance is 50 m 
So you need the average velocity to solve. Or know something about the acceleration curve. 

For example if the motorcycle stopped in the first 5 metres waited for an hour then accelerated up to 20 m/s by 50 m the average acceleration would be different then if it uniformly accelerated.
