A bicycle increases its velocity from 10 km/h to 15 km/h in 6 seconds. Calculate its acceleration.
Dear student,
bicyle's initial velocity is given as u=10km/h=50/18 m/s and finl velocity v=15km/h=75/18m/s
time t=6seconds
( 1km/h= 5/18 mps)
v=u+at
here a is the acceleration,
so, 75/18=50/18 + 6a
75=50+ 108a
a =0.23 m/s2
Regards
