Question

What is the average acceleration of an object that goes from rest to a

speed of 7m/s in just 0.1s?

Answer 1

• Initial velocity=u=0m/s
• Final velocity=v=7m/s
• Time=t=0.1s

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

`\\ \sf\longmapsto Acceleration=(7-0)/(0.1)`

`\\ \sf\longmapsto Acceleration=(7)/(0.1)`

`\\ \sf\longmapsto Acceleration=70m/s^2`
