Question

Can anyone help me plsss​

Answer 1

#a

• Distance travelled=30m

#b

• Distance travelled=50m

#c

• Total distance =50m+30m=80m

#d

`\\ \sf\bull\dashrightarrow Avg\:speed=(Total\:Distance)/(Total\:Time)=(30)/(10)=3m/s`

#e

`\\ \sf\bull\dashrightarrow Avg\:Speed=(50)/(5)=10m/s`

#f

`\\ \sf\bull\dashrightarrow Avg\:Speed=(50+30)/(10+5)=(80)/(15)=5.3m/s`

#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

`\\ \sf\bull\dashrightarrow Avg\:velocity=(Total\:Displacement)/(Time)=(20)/(15)=1.3m/s`
