Question

. A bicycle increases its velocity from 10 km/h to 15 km/h in 6 seconds. Calculate its
acceleration​

Answer 1

Answer:

0.83km/h

Explanation:a=v-u/t

a=15-10/6=0.83

Answer 2

Initial Velocity = u = 10 km/h = 10×5/18 = 50/18 m/s

Final Velocity = v = 15 km/h = 15×5/18 = 75/18 m/s

And time = t = 6 sec.

So, Acceleration = a =>

a = (v - u)/t

a = (75-50) / 18×6

a = 25 / 108

a = 0.2315 m/s^2......●
