Particle P released from rest at O. Falls freely under gravity until reaching point A which is $1.25$m below O.
(i) Find speed of P at A and time taken for P to reach A.
P continues to fall, but now its downward acceleration $t$ seconds after passing through A is $(10-0.3t)$ metres per second square.
(ii) Find the total distance P has fallen, $3$ s after being released from O.
I have solved (i) and the speed is $5$ m/s and time is $0.5$ s. (ii) is easy, I think, but the given answer is $44.2$ m, while my answer is coming $43.7$ m.
