saifoo.khan · Answer

integrate using limits.

saifoo.khan · Answer

$$\int\limits_{0}^{3} 2t^2 + t -6$$

anonymous · Answer

part a) find displacement of the car between t=0 & t=3
i figured this out and got 4.5 feet (v(t) is expressed in feet/sec btw)
part b) find distance covered by the car duing this period of time
part b i'm having trouble with, don't know what the hell it's asking

anonymous · Answer

part b sounds exactly like part a

anonymous · Answer

the answer is supposed to be 15.75ft if that helps

disp is vector while dist is scalar, you know about this right?

saifoo.khan · Answer

4.5 is the disp i think. which is above the x-axis.

saifoo.khan · Answer

if you graph the curve. you will get something like,
|dw:1335237647776:dw|
