Question

The graph below shows how the speed of a bus changes during part of a journey.


16. In segment 0-A, the bus is ___________ . Its speed changes from 0 to 10 m/s in 5 seconds.
accelerating********
accelerating negatively
at a constant speed
at rest

17. In segment A-B, the bus is moving __________ of 10 m/s for 5 seconds.
accelerating
accelerating negatively
at a constant speed*******
at rest


18. In segment B-C, the bus is ____________. It is slowing down from 10 m/s to rest in 3 seconds.
accelerating
accelerating negatively****

21. Calculate the acceleration of the bus from point D to E. Show your work.

21. What is the acceleration of the bus from point D to E in meters per second per second

Can anyone help me with the last two? Also check if im right for the others please :)

Here is the graph. add these numbers to the end 14610344

Answer 2

acceleration is change in velocity divided by time interval.
So, look at the graph and divide the speed change by the time to took.

The acceleration is just the slope of the velocity line.

Hint: consider the units. Acceleration is in m/s^2
So, divide change in velocity (m/s) by change in time (s)
