Question

the displacement (in meters) of an object is give by [equation given] where 't' is the time in seconds.
a) find the average velocity for t=1 to t=4
b) find the instantaneous velocity at t=3

Answer 1

\[\huge s(t)= 2t^2+3t+1 \]

Answer 2

Can u find s'(t)

Answer 3

no this is for a advanced function's class i am not allowed to use calc :(

Answer 4

Then find s(4) and s(1)

Answer 5

So, average velocity for t=1 and t=4 is {s(4)-s(1)}/(4-1)

Answer 6

can u find it?

Answer 7

I'm sorry, but how are you expected to do this without calculus?
