Answer:
first,let us convert both speed in m/s.
conversion from km/h to m/s
1km=1000m
1hour=60 minutes=3600s
1km/h = 1000m/3600s
1km/h=5/18m/s
car 1
initial velocity=52m/h
52*5/18m/s
130/18m/s
=14.44m/s
initial velocity=0m/s
time = 5 second
now,
car 2
initial velocity=3km/h
= 3*5/18m/s
5/6 m/s
0.833m/s
initial velocity=0 m/s
time = 10 second
