Homework Statement



Hi am a physics beginner love it but seem to have issues with understanding Linear motion .. Anyway i have a question ..will be glad if could help .
" A car moves along a road in such a way that the distance x ,traveled in a time t ,is given by x=a+bt(to the power 3) where A and B have constant values of 3.5m and 2.5ms-3 respectively .
Derive expressions for the velocity and acceleration as a function of time and calculate the values of displacement ,velocity and acceleration at t=2.0s .
Then draw a rough sketch to show how the velocity and acceleration vary with time..
Thanks ...

ok so you know that x=A+Bt3 and you are given A and B, now write down the equation of x with A and B with their respective values.

How do you find velocity when given displacement as a function of time? (i.e. what is the relation between velocity, displacement and time?

Similar for acceleration.


EDIT: Read up on http://en.wikipedia.org/wiki/Kinematics"
