A bus decreases its speed from \( 80 km h ^{-1} \) to \( 60 km h ^{-1} \) in \( 5 s \). Find the acceleration of the bus. |
Answer»
v = u + at is the first equation of motion. where, u is initial velocity v is the final velocity a is acceleration t is the time period v = u + at a = v – u/t a = 16.7 – (22.2/5) a = -1.1 m/s2
