Soalan 2
Pecutan, a ms–2, bagi suatu zarah yang bergerak di sepanjang satu garis lurus pada masa[br]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[br][br][i]The acceleration, a ms–2, of a particle moving along a straight line at time[br]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[br][/i][br](a) pecutannya ialah 4 ms–2 [br][br][i](a) its acceleration is 4 ms–2[/i][br]
(b) zarah berada dalam keadaan pegun[br][br][i](b) the particle is at rest[/i]
