Question

Convert 50km/hr into m/s using dimensional analysis?

Answer 1

Step-by-step explanation:

1 km=1000 m

1 hour =60 min =60*60 sec=3600 sec

Now put 1000 m instead of km and 3600 sec instead of hour in the given expression.

=50 km/hour

=50*1000 m/3600 sec

=500 m/36 sec

=13.89 m/s

Answer 2

= 13.89 m/s

Step-by-step explanation:

km 1000 m 1 hr

50 ----- x ---------- x ------------

hr 1 km 3600 secs

= 13.89 m/s
