Question

A bus decreases its speed from 70km/h to 50km/h in 5 sec.Find its acceleration of the bus.

Answer 1

$a = \frac{v - u}{t} \\ a = \frac{ - 20}{5} \\ a = - 4$

Answer 2

here you go ☆☆

given:-

▪u=70 km/h
= 22.22m/s
▪v= 50km/h
= 16.66m/s
▪t= 5s

▪as we know,

▪$a = \frac{v - u}{t}$

▪$\frac{ 16.66 \times 22.22}{5}$

▪a= 1.11m/s^2

hope it helps you....
