Homework Statement
Moves at G(f)=t^2-4t+3
a. Find displacement at 2 sec
b. Find average velocity at 4 sec
c. Find instantaneous velocity at t=4
d. Find acceleration at t= 4
Homework Equations
Instantaneous rate of change
Displacement
The Attempt at a Solution
f'= 2t-4 (So this would be the velocity then?)
f''=2 (Acceleration?)
How do I go about finding it at specific values? Just plug it in?
For example...
Find average velocity at 4 sec:
2(4)-4= 4
