Question

A bus increase its speed from 36 km/h to 72 km/h in 10 seconds . it's acceleration in decimals solved problems​

Answer 1

Answer:

the correct answer is 1 m/ s²

Explanation:

in the given question we have

u=36 km/hr =36× 5/18 m/s=10m/s

v= 72 km/hr=72× 5/18 m/s=20m/s

t=10 s

a=?

we know the formula

v= u +at

20 = 10+ a 10

20-10 =10 a

10 = 10 a

a = 1 m/s ²
