Question

A bicycle moves with a constant velocity of 5 km/h
for 10 minutes and then decelerates at the rate
1 km/h^2?, till it stops. Find the total distance covered
by the bicycle​

Answer 1

Answer:

v=5km /hr

v=5×5/18

v=25/18m/sec

time=10 min

= 600sec

a=1km/hr²

a=5/18m/sec²

from newton 2law

s=ut+1/2at²

s=1/2×5/18×600×600

s=50000m

s=50km
