Find the uniformed acceleration that causes a car's velocity to increase from 32 ms to 96 ms in a period of 8.0 seconds
🔄 Click to see definition
Definition1/17
The average uninformed acceleration is (delta-V) / (delta-T). Delta-V = (96 - 32) = 64 m/s. Delta-T = 8.0 seconds. A = (64 m/s) / (8.0 sec) = 8 m/s2

Assuming that his acceleration was linear (ie. that he slowed
down at a perfectly steady rate), then you can say his velocity at
any point in those eight seconds was:
21 - t(21 / 8) m/s
To get the distance covered in that time, you can simply take
the area under that line between 0 seconds and eight seconds.
Because it's linear, this is very easy. You're dealing with a right
triangle that is 8 seconds wide and 21 meters per second tall. With
a triangle, the area is equal to half it's width times it's height,
so the equation is:
d = 21m/s * 8s / 2
∴d = 168m / 2
∴d = 84m.
So he traveled 84 meters in those 8 seconds, and probably scared
the bejeebers out of that poor deer.
