A dragster, starting from rest, accelerates at 28 m/s/s for 4.5 s. Then the parachute comes out and it slows to 46 m/s in 10 s. Determine its acceleration in those 10 s when the parachute is deployed. Show your working.

First find acceleration before opening

parachute

Now

After opening the parachute the Final velocity calculated above would become initial velocity

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

the answer would be 32*f
