Answer 1

Answer:

3.6

Explanation:

a car accelerates uniformly from 18km/h to 36km/h in 5 minutes th

en acceleration is

36-18/5

Answer 2

Answer:

Initial speed (u) = 18km/h = 5 m/s

final speed (v) = 36km/h = 10m/s

acceleration (a)=(v-u)/t

= (10-5)/5

= 1 m/s2

Distance travelled (s) = ut +1/2 at2

= 5×5+1/2×1×(5)2

= 37.5 m
