Amfani da kiyaye makamashin injiniya don motsi a kan jirgin sama mai karkata - matsaloli da mafita

1. Toshe yana zamewa ƙasa a kan wani jirgin sama mai santsi ba tare da gogayya ba . Menene saurin toshe idan ya faɗi ƙasa. Saurin gudu saboda nauyi shine 10 m/s ²

An sani:

Tsawo (h) = mita 8

Saurin gudu saboda nauyi (g) = 10 m/s ²

Ana so : saurin gudu (v)

Mafita :

Makamashin injina na farko (ME _o ) = makamashin ƙarfin nauyi (PE)

ME _o = PE = mgh = m (10)(8) = 80 m

Makamashin injiniya na ƙarshe (ME _t ) = makamashin motsi (KE)

ME _t = KE = ½ mv ²

Ka'idar kiyaye makamashin injiniya ta bayyana cewa makamashin injiniya na farko = makamashin injiniya na ƙarshe:

NI _o = NI _t

80 m = ½ mv ²

80 = ½ v ²

160 = v ²

v = √160 = √(16)(10) = 4√10 m/s

2. Abu mai nauyin kilogiram 1 yana zamewa ƙasa tare da mita 8. Kayyade kuzarin motsi bayan abin ya motsa tare da mita 5… Hanzarta saboda nauyi g = 10 m/s ²

An sani:

Nauyi (m) = 0.2 kg

d = mita 5

Saurin gudu saboda nauyi (g) = 10 m/s ²

Ana so : kuzarin motsi (KE)

Magani:

zunubi 30 ^o = h / d

0.5 = h / 5

h = (0.5)(5) = mita 2.5

Canjin tsayin abu shine mita 2.5.

Makamashin injina na farko (ME _o ) = makamashin ƙarfin nauyi (PE)

ME _o = PE = mgh = (1)(10)(2.5) = Joules 25

Makamashin injiniya na ƙarshe (ME _t ) = makamashin motsi (KE)

ME _t = KE

Ka'idar kiyaye makamashin injiniya ta bayyana cewa makamashin injiniya na farko = makamashin injiniya na ƙarshe:

NI _o = NI _t

25 = KE

Makamashin motsi = Joules 25.
