Respuesta :

#a

  • Distance travelled=30m

#b

  • Distance travelled=50m

#c

  • Total distance =50m+30m=80m

#d

[tex]\\ \sf\bull\dashrightarrow Avg\:speed=\dfrac{Total\:Distance}{Total\:Time}=\dfrac{30}{10}=3m/s[/tex]

#e

[tex]\\ \sf\bull\dashrightarrow Avg\:Speed=\dfrac{50}{5}=10m/s[/tex]

#f

[tex]\\ \sf\bull\dashrightarrow Avg\:Speed=\dfrac{50+30}{10+5}=\dfrac{80}{15}=5.3m/s[/tex]

#g

  • Displacement=30m

#h

  • Displacement=50m

#i

  • Total displacement=30-50=|-20|=20m

#j

  • Same answer as option d

#k

  • Same ans as option e

#l

[tex]\\ \sf\bull\dashrightarrow Avg\:velocity=\dfrac{Total\:Displacement}{Time}=\dfrac{20}{15}=1.3m/s[/tex]
