Question

a car is travelling at a velocityof 10.8 km/hr and attains a velocity 54km/hr in 6sec what it's acceleration​

Answer 1

Answer:

7.2km/hr^2

Explanation:

u =10.8km/hr

v=54km/hr

t=6sec

a=?

from

v=u+at

54=10.8+6a

54-10.8=6a

43.2=6a

43.2÷6=a

7.2=a

hence acceleration is 7.2km/hr^2
