Question

Kaya is riding her dirt bike eastward on a dirt road. She spots a pothole ahead. Kaya slows from 20.0 m/s to 6 m/s in 6.0 s. What is her acceleration?

Answer 1

• initial velocity=u=20m/s
• Final velocity=v=6m/s
• Time=t=6s

`\\ \sf\longmapsto Acceleration=(v-u)/(t)`

`\\ \sf\longmapsto Acceleration=(6-20)/(6)`

`\\ \sf\longmapsto Acceleration=(-14)/(6)`

`\\ \sf\longmapsto Acceleration=-2.3m/s^2`
