Question

a bicycle moves with a constant velocity of 5 km/h for 10 min and then decelerate at the rate of 1km/h2 till it stop . find the total distance covered by a bicycle

Answer 1

u = 5 km per hour
v = 0 km/h
a = -1 km/h^2
s = ?
using third equation of motion
v^2-u^2=2as
(0)^2-(5)^2 =2(-1)s
-25 = -2s
12.5= s
12.5 km covered by the cycle
