Question

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

Answer 1

@
Changing km/h in m/s
15km/h=15×5/18=4.16m/s
10km/h=10×5/18=2.7m/s
______
a=v-u/t
=>4.16-2.7/6
=>3.71 m/s²
acceleration = 3.71 m/s²
@:-)

Answer 2

first convert velo. into m\s by multiplying it with 5/18 and then from find difference b/w initial and final velocity and divide by time
