Homework Statement
I have to calculate the displacements from a velocitytime graph to make a positiontime graph.
The velocitytime graph from the question is attached.
Homework Equations
d=vt
The Attempt at a Solution
To calculate the values for a positiontime graph, I first converted all the velocities from km/h to km/min to match the time.
The truck travels at 70 km/h (1.16 km/min) for 10 mins: 1.16 x 10 = 11.6
It then travels at 80 km/h (1.33 km/min) for 30 mins: 1.33 x 30 = 40
It then travels at 75 km/h (1.125 km/min) for 5 mins: 1.25 x 5 = 6.25
It then travels at 60 km/h (1.0 km/min) for 2.5 mins: 1.0 x 2.5 = 2.5
And then travels at 55 km/h (0.9 km/min) for 22.5 mins: 0.91 x 22.5 = 20.6
I drew a positiontime graph which is attached. I just want to know if I did this right because the graph I made looks a little weird to me.
