Question

.A bus decreased it's speed from 80km/ hr to 60km/hr. In 5 sec. Calculate it's acceleration​

Answer 1

Answer:

Hi friends

Explanation:

U= initial velocity= 80 km/h = 22.2 m/s

v= final velocity = 60 km/h = 16.7 m/s

t= time = 5 s

a= acceleration = ?

a=v-u/t

a= 16.7-22.2/5

a= -5.5/5

Therefore, a=-1.1 m/s^2

pls mark me brainliest

Answer 2

80+60/5

140/5

-28m/sec^2
