Question

a bus increase its speed from 20km/hr to 50km/hr in 10 second. find its acceleration

Answer 1

Answer:

3m/s²

Explanation:

Given that

U(initial velocity) =20km/h,

V(final velocity) =50km/h

t (time taken) =10 sec

now 'a' be acceleration of the bus

now. a=v-u/t

=> a=50-20/10

=> a=30/10

=> a=3 m/s²
