Explanation:
Initial Velocity (u) = o m/s
Final Velocity (V) =(72*1000)/1*60*60 m/s
= 20m/s
time (t) =8 sec
Acceleration(a)= v-u /t
=(20-0)/8
=2.5 m/s^2
Answer:
5N
(25 N - 20 N = 5 N)
<u><em>Frictional force refers to the force generated by two surfaces that contacts and slide against each other.</em></u>
