Question

4. If a car attains a speed of 36km/h from rest in 12 minutes time, what is the distance
covered​

Answer 1

Answer:

here u = 0 , v=36 km/hr t= 12 min

First convert velocity into m/s and time into seconds

therefore ,

v= 36*(1000 / 60 *60 ) m/s

= 10 m/s

Time = 12 min

= 12 *60 seconds

= 720 s

WE KNOW THAT

v=u+ at

10 = 0+a*720

a = 10/720 m/s²

= 1/72 m/s²

We know that ,

v² - u² = 2as

=> 10² - 0 ² = 2*(1/72 ) *s

=> 100 = s/36

=> s= 36*100

= 3600 m

Therefore Distance Traveled = 3600 m
