# Velocity, Time, Distance of a Rock After it has been Thrown

If a rock is thrown into the air on small planet with a velocity of 25 meters/second, its height in meters after t seconds is given by V = 25t ? 4.9t2. Find the velocity of the rock when t=3

A particle moves along a straight line and its position at time t is given by s(t) = 2t3 ? 27t2 + 108t where s is measured in meters and t in seconds.

Find the velocity of the particle at time t = 0: _______________ meters/second.

The particle stops moving (i.e. is in a rest) twice, once when t=A and again at t = B where A < B.

A is ____________seconds,

and B is _____________ seconds.

What is the position of the particle at time 18? ________________________ meters.

Finally, what is the TOTAL distance the particle travels between time 0 and time 18? ____________________________ meters.
