Answer:
[tex]a=5.43\ m/s^2[/tex]
Step-by-step explanation:
Given that,
Initial speed of a vehicle, u = 25 km/hr = 6.95 m/s
Final speed of a vehicle, v = 1200 km/hr = 333.34 m/s
Time, t = 60 s
We need to find the acceleration of the vehicle. It is equal to the rate of change of velocity. It can be given by :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{333.34 -6.95 }{60}\\\\a=5.43\ m/s^2[/tex]
So, the acceleration of the vehicle is [tex]5.43\ m/s^2[/tex].
