Question

A car accelerates uniformly from 18 km/hr to 36 km/hr in 5 mins. The acceleration is​

Answer 1

Answer:

acceleration of the car = 0.0166 m/s²

Explanation:

Let

Initial speed be U = 18 kmph = (5/18)*18 = 5 m/s

Final speed be V = 36 kmph = (5/18)*36 = 10 m/s

Time taken to change speed be T = 5 min = 5*60 = 300 s

Now we know,

Acceleration = (Final speed - Initial speed)/Time taken

=> a = (V - U)/T = (10-5)/300

=> a = 0.0166 m/s²
