Latihan Kendiri 8.7 Soalan 2

Pecutan, a ms–2, bagi suatu zarah yang bergerak di sepanjang satu garis lurus pada masa t saat selepas melalui satu titik tetap O diberi oleh a = 12t – 8. Diberi halaju zarah, t = 1 saat selepas melalui O ialah –10 ms–1. Cari sesaran seketika zarah itu, dalam m, apabila The acceleration, a ms–2, of a particle moving along a straight line at time t seconds after passing a fixed point O is given by a = 12t – 8. Given the particle's velocity, t = 1 second after passing O is –10 ms–1. Find the instantaneous displacement of the particle, in m, when (a) pecutannya ialah 4 ms–2 (a) its acceleration is 4 ms–2

(b) zarah berada dalam keadaan pegun (b) the particle is at rest
