Question

a bicycle increases its velocity from 10 km per hour in 6 seconds calculate its acceleration in metre per second square

Answer 1

initial velocity u =10km/h=10000/3600m/s
u=2.7m/s
final velocity V =15km/h=15000/3600=4.16m/s
time t =6s
using V =u+at
or,at=V-u
6a=4.16-2.7
a=1.46/6
a=0.25m/Sq. sec
a

Answer 2

that is right answer
