Question

A bus is starts from rest and attian40kmh-¹ velocity after10 second ? calculte acceleration in kmh-² , ms-²​

Answer 1

Answer:

Explanation:

u = 0 km/h = 0 m/s

v = 40 km/h = 40× 5/ 18 = 11.11 m/s

t = 10s

a = v - u / t

  = 11.11 m/s - 0 m/s / 10 s

  = 1.11 m/s²

in km/h

1.11 × 18 / 5

4 km/h (approx.)
