A mole moves in its tunnel and its velocity is explained with the equation
v(t) = 0,15t – 0,032t 2, for the time from t=0 to t=6.
1) How far does the mole go before it returns?
2) What distance does the mole go from t=0 s to t=4 s?
3) What is the highest acceleration of the mole, and when is it the highest?
4) What is the maximum speed of the mole and when does she obtain this speed?
5) What is the velocity of the mole when t=3 s and when is the speed of the mole when the speed is zero?
