Misalai 2 na amfani da dokokin Newton a kan jirgin sama mai santsi (ba tare da gogayya ba)
1. Nauyin tubalin shine kilogiram 2, hanzarin nauyi saboda nauyi = 10 m/s2Kayyade (a) ƙarfin da ke haifar da hanzarta toshewar (b) girman saurin toshewar.
Tattaunawa
An sani :
Nauyin tubali (m) = 2 kg
Saurin gudu saboda nauyi (g) = 10 m/s2
Nauyin tolo (w) = mg = (2)(10) = 20 Newton
wx = w zunubi 30 = (20)(0,5) = 10 Newtons
wy = w cos 30 = (20)(0,5√3) = 10√3 Newtons
Amsa:
(A) ƙarfin da ke haifar da hakan wanda ke hanzarta toshewar
Jirgin sama mai santsi wanda ake ɗauka babu gogayya. Saboda haka ƙarfin da ke shafar motsin toshewar shine kawai wx
(B) girman hanzarin toshewar
Girman saurin toshe shine 5 m/s2, alkiblar hanzarta toshewar tana ƙasa.
2. Toshe yana kan wani santsi, mara gauraye. Nauyin toshe shine kilogiram 3, kuma saurin gudu saboda nauyi shine mita 10/s.2. Kayyade girman ƙarfin F idan (a) toshewar har yanzu (b) toshewar ta motsa ƙasa tare da saurin gudu na 2 m/s2 (c) toshe yana motsawa sama tare da saurin gudu na 2 m/s akai-akai2.
Tattaunawa
An sani :
Nauyin tubali (m) = 3 kg
Saurin gudu saboda nauyi (g) = 10 m/s2
Nauyin tolo (w) = mg = (3)(10) = 30 Newton
wx = w zunubi 30 = (30)(0,5) = 15 Newtons
wy = w cos 30 = (30)(0,5√3) = 15√3Newtons
Amsa:
(a) Ka tantance F idan toshewar ta tsaya.
Dokar farko ta Newton ta bayyana cewa abu yana hutawa idan ƙarfin da aka samu ya zama sifili.
(b) Kayyade F idan toshen ya koma ƙasa tare da saurin gudu na 2 m/s2
(c) Kayyade F idan toshen ya motsa sama tare da saurin gudu na 2 m/s akai-akai2
[Turanci: Motsi a kan jirgin sama mai karkata ba tare da ƙarfin gogayya ba]
