A bus is moving at 10 M per second on a straight road a scooterist 80 m behind moving at 5 M per second wishes to overtake the bus in hundred seconds find the acceleration required for scooterist to do this

Relative velocity of the two vehicles =velocity of the scooter - velocity of the bus
5m/s - 10m/s= - 5 m/s
(this means that the distance between them is increasing 5 meters each second)
(note: if two objects are traveling in the same direction then the relative speed is equal to the difference between their speeds and if they are traveling in opposite direction then their relative is speed equal to the sum of their speeds.)
u = -5m/s
s = 80m
t = 100 s
a =?
We know that,
s = ut + 1/2at²
80m = -5m/s × 100 s + 1/2a × (100 s)²
80m = -500m + 5000a s²
580m = 5000a s²
a = 580m/5000s²
a = 0.116 m/s²
a ≈ 0.12 m/s²
Hope it help will you.
