Puisano
Hoa tsebahala hore:
d = 1 / (mela e 4000 / cm) = 0,00025 cm = 2,5 x 10^-4 cm = 2,5 x 10^-6 m
l = 1 m
y = 30 cm = 0,3 m

4 Mehlala ea lebelo le tloaelehileng le lebelo le tloaelehileng

1. Koloi e tsamaea ka ho toba botjhabela ka limithara tse 100 ka metsotsoana e 4 ebe e tsamaea ka ho toba bophirima ka limithara tse 50 ka motsotsoana o le mong. lebelo le tloaelehileng dan tao lebelo le tloaelehileng mobile.
Puisano

Sebaka = limithara tse 100 + limithara tse 50 = limithara tse 150
Palo ea ho falla = limithara tse 100 - limithara tse 50 = limithara tse 50 'me tsela eo ho falla ho eang ka eona e lebile bochabela.
Kakaretso ea nako = metsotsoana e 4 + motsotsoana o le 1 = metsotsoana e 5.

4 Mehlala ea lipotso tsa bohōle le ho falla

1. Koloi e tsamaea ka ho toba botjhabela ka limithara tse 100 ebe e tsamaea ka ho toba bophirima ka limithara tse 50. Fumana sebaka le ho falla ha koloi ho tloha moo e leng teng qalong.
Puisano
Sebaka = limithara tse 100 + limithara tse 50 = limithara tse 150
Palo ea ho falla = limithara tse 100 - limithara tse 50 = limithara tse 50 'me tsela eo ho falla ho eang ka eona e lebile bochabela.

Puisano
Ha ho foromo (sebelisa mokhoa oa ho nahana) :
Lebelo la koloi le fetoha ho 20 m/s kamora metsotsoana e 10. Sena se bolela hore lebelo la koloi le eketseha ka 2 m/s motsotsoana o mong le o mong. Kahoo, lebelo la koloi ke 2 m/s ka motsotsoana = 2 m/s ka motsotsoana = 2 m/s².
Ho sebelisa foromo :
Hoa tsebahala hore:
