Question

A Scooterist travelling with a velocity
of 20km/hr, accelerate with an accelera-
- tion of 0.10 ms^2 . After what time will
it velocity be 38 km / hr​

Answer 1

Answer:

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

Answer 2

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
