Answer:
the final velocity of the bus is -20 m/s.
Explanation:
Given;
initial velocity of the bus, u = 20 m/s
deceleration of the bus, -a = 8 m/s²
time of motion, t = 5 s
The final velocity of the bus is calculated as;
v = u + at
v = 20 + (-8 x 5)
v = 20 - 40
v = -20 m/s.
Therefore, the final velocity of the bus is -20 m/s.
