4 2. A particle P moves along a straight line. At time t seconds, the velocity v m s−1 of P is modelled as v = 10t − t 2 − k t 0 where k is a constant. (a) Find the acceleration of P at time t seconds. (2) The particle P is instantaneously at rest when t = 6 (b) Find the other value of t when P is instantaneously at rest. (4) (c) Find the total distance travelled by P in the interval 0 t 6 (4) _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________
