Question

the below data shows the speedometer of the car calculate the acceleration of the car time at 10:00 a.m. speedometer 40 kilometre per hour time 8:30 a.m. speedometer 75 kilometre per hour

Answer 1

Answer:

Given:-

Initial velocity (u) = 40km/hr = 11.1111m/s

Final velocity (v) = 75km/hr = 20.8333m/s

Time (t1) = 8hrs 30 min = 30600sec

Time (t2) = 10hrs = 36000sec

Change in time = (t2-t1) = 36000-30600

= 5400sec

To find:-

Accleration

By applying, v - u = at

20.8333-11.1111 = a×5400

9.7222 = 5400a

a = 0.0018m/s^2.
