Question

A car is traveling 20kmph it speeds upto 60kmph in 6 hours . Find it's average velocity and acceleration​

Answer 1

Answer:

a= 50/27 m/s²

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
