Question

1) A train accelerates from 36 km/hr to 54 km/hr in 10
s. Find acceleration?​

Answer 1

Explanation:

a=v-u/t

=54-36/10

=18/10

=9/5. ans

Answer 2

Explanation:

as, acceleration=final velocity -initial velocity/time

u=36km/h=10m/s

v=54km/h=15m/s

t=10s

a=v-u/t

a=15m/s-10m/s

10s

a=5m/s

10s

a=0.5m/s*s
