Question

A bicycle moves with a constant velocity of 5 km/h for 10 minutes and then decelerates

at the rate 1 km/h2

, till it stops. Find the total distance covered by the bicycle.

Answer 1

distance with constant velocity=5×1/6=5/6 km
v^2=u^2 +2as
0=25-2×1×s
s=25/2km
total distance=25/2+ 5/6
=80/6
=40/3 km
