Question

a bicycle changes its velocity from 10km/h to 15 km/h in 5 hours calculate acceleration in m/s square

Answer 1

Answer:

Explanation: convert km to m first . So 10km/h is 2.7m/s and 15km/h is 4.1m/s.5 hours is 5*3600 =18000 s

Acceleration is change in velocity by total time taken

A= v2-v1/t

= 4.1-2.7 /18000

=1.4/18000

=0.000078 m/s

Hope this answer is correct!
