Question

A vehicle accelerates from 25 km/hr to 1200 km/hr in 60 sec. What is the vehicle's acceleration?

Answer 1

Answer:

$a=5.43\ m/s^2$

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 :

$a=\dfrac{v-u}{t}\\\\a=\dfrac{333.34 -6.95 }{60}\\\\a=5.43\ m/s^2$

So, the acceleration of the vehicle is $5.43\ m/s^2$.
