Question

a car is travelling at 20km)h it speed upto 60km/h in 6 second what is its acceleration​

Answer 1

Answer:

hlo

ji

using first equation of motion ,

v = u+at

50/3 = 50/9 + a(6)

50/3 -50/9 = 6a

150/9-50/9 = 6a

100/9 = 6a

=> 100/9×6 = a

=> 100/54 = a

=> 50/27 m/s² = a

=> 1.85 m/s² = a

I think

Answer 2

Answer:

Hope it's helpful for you

Explanation:

u= 20 km/h = 20*5/18= 50/9 m/s

v= 60 km/h = 60*5/18= 50/3 m/s

t= 6 s

a= v-u/t

= = 50/3-50/9-6

= = 100/9=6

= 100/9×1/6 =

= 50/27 m/s^2
