Question

A car achieves its speed
72 kmph in 30 seconds after start.
find accleration and speed.​

Answer 1

Answer:

0.66m/s^2

Explanation:

• Time(t)=30second
• Intial velocity (u)=0
• Final velocity (v)=72km/h

(We have to convert km/h into m/s)

therefore,72*5/18=20m/s

Acceleration (a)=v-u/t(by sbtuting the value)

20-0/30

20/30=0.66m/s^2
