Question

A bicycle increases its velocity from 18km/h to 72km/h in 10 second calculate its acceleration

Answer 1

hey dear
here is your answer

given data :

initial velocity (u) = 18 km/hr = 5 m/s

final velocity (v) = 72 km/hr = 20 m/s

time (t) = 10 seconds

acceleration (a) = ?

so, by using first equation oif motion

v = u+at

20 = 5+10a

10a = 15

a = 1.5 m/s²

hope it helps :)
