and acceleration = velocity change ÷ time. To find the distance travelled, look at the area under the graph. In the first 10 seconds this is the area of the triangle, ½ × 10 s × 40 m/s = 200 m.

then I can calculate the average speed and the time to run. But I don't know the final velocity. Let me use the time that I just calculated and the acceleration to determine this final velocity.

They are afraid to embrace the power of the graph ... to find the acceleration from this distance-time data. Let's go back to our kinematic equation (assuming we start with zero velocity).

Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken ... to 28 m/s. Calculate the ...
