Question

What is the acceleration of a car that goes from 5m/s to 95m/s in 10s?

A. 45m/s^2
B. 100m/s^2
C. -9m/s^2
D. 9m/s^2

Answer 1

• Initial velocity=u=5m/s
• Final velocity=95m/s=v
• Time=t=10s

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

`\\ \tt\longmapsto Acceleration=(95-5)/(10)`

`\\ \tt\longmapsto Acceleration=(90)/(10)`

`\\ \tt\longmapsto Acceleration=9m/s^2`
