A particle P P\,P moves in a straight line so that, at time t t\,t seconds, its velocity v m s−1v \text{ m s}^{-1}v m s−1 is given by
v={7t−t20≤t≤510−2tt>5 v = \begin{cases} 7t - t^2 & 0 \leq t \leq 5 \\ 10 - 2t & t > 5 \end{cases} v={7t−t210−2t0≤t≤5t>5Find the acceleration of P P\,P when t=4t = 4t=4
Find the total distance traveled by P P\,P in the first 10 seconds.
