Vectors na raka'a - matsaloli da mafita

1. Abu yana motsawa a gudun v = (2i − 1.5j) m/s. Menene matsar da abu bayan daƙiƙa 4?

An sani:

Sashen kwance na saurin (v _x ) = 2 m/s

Bangaren tsaye na saurin (v _y ) = 1.5 m/s

Tazarar lokaci (t) = daƙiƙa 4

Ana nema: Gudun hijira

Matsar da Vector - matsaloli da mafita

1. Mutum yana tafiya daga wuri A zuwa wuri B, mita 600 a arewa; sannan zuwa wurin C, mita 400 a yamma; sannan zuwa wurin D, mita 200 a kudu; sannan ya ƙare a wuri E, mita 700 a gabas. Menene girman ƙaura?

Magani:

An sani:

AF = AB – BF = AB – CD = 600 – 200 = 400 m

EF = DE - DF = DE - BC = 700 - 400 = 300 m

Ƙara vectors ta amfani da abubuwan haɗin kai - matsaloli da mafita

1. Vectors guda uku kamar yadda aka nuna a hoton da ke ƙasa.

V₁ = 30

V ₂ = 30

V3 = ₄₀

Menene vectors ɗin da suka haifar.

An sani:

V ₁ = 30, kusurwa tsakanin V ₁ da x axis = 30 ^o

Zane-zanen motsi na layi - matsaloli da mafita

1. Zana tazara (tsaye) da lokaci (a kwance) kamar yadda aka nuna a cikin hoton da ke ƙasa. Wani abu da aka huta da lamba…

Magani:

Lamba ta 3, wadda aka nuna ta hanyar layi madaidaiciya.

Matsakaicin gudu - matsaloli da mafita

1. Wani yana zagaye murabba'i mai tsawon mita 400 da faɗin mita 100, sau 12 a cikin awa 1. Menene matsakaicin gudu da matsakaicin gudu?

An sani:

Tsawon murabba'i mai kusurwa huɗu = mita 400

Faɗin murabba'i mai kusurwa huɗu = mita 100

Da'irar murabba'i mai kusurwa huɗu = (mita 2 x 400) + (mita 2 x 100) = mita 800 + mita 200 = mita 1000

Nisa = mita 12 x 1000 = mita 12,000 = kilomita 12

Ka'idar Baƙi - matsaloli da mafita

1. Ruwan gram 200 a digiri 30 na Celsius a gauraya da ruwan gram 100 a digiri 90 na Celsius. Takamaiman zafin ruwan = 1 cal.gram ⁻¹ °C ⁻¹ . A tantance zafin ƙarshe na cakuda!

An sani:

Nauyin ruwa 2 (m ₁ ) = gram 200

Zafin ruwa 1 (T1 ) ₌ 30 ^oC

Nauyin ruwa 2 (m2 ₎ = gram 100

10 Dynamics Object da aka haɗa ta hanyar igiya akan injin Atwood - Matsaloli da Magani

1. Toshe A mai nauyin kilogiram 5, an sanya shi a kan jirgin sama mai santsi a kwance. Toshe B mai nauyin kilogiram 3 a rataye a ƙarshen igiyar da aka haɗa da toshe A a kan injin jan ƙarfe. Saurin gudu saboda nauyi shine 10 m/s ^2. Menene saurin gudu na toshe biyu?

An sani:

Nauyin toshe A (m)_A) = 5 kg

Nauyin tubalin B (m _B ) = 3 kg

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

Motsin zagaye - matsaloli da mafita

1. Abu mai nauyin kilogiram 10 yana motsawa a cikin da'ira a gudun da ba ya canzawa 4 m/s. Idan radius na da'irar mita 0.5 ne, to:

1) Mitar da'ira ita ce 4/π Hz

2) Hawan centripetal shine 32 ms ^-2

3) Ƙarfin tsakiya shine 320 N

4) Lokacin shine 4π s.

Wadanne maganganu ne na gaskiya?

Motsin faɗuwa kyauta - matsaloli da mafita

1. Dutse yana faɗuwa cikin sauƙi daga tsayin mita 45. Idan saurin da aka samu sakamakon nauyi ya kai 10 ms ^-2 , menene saurin dutsen idan ya faɗi ƙasa?

An sani:

Tsawo (h) = mita 45

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

Ana so: Saurin ƙarshe na dutsen lokacin da ya faɗi ƙasa (v _t )
