Question

2. A bus decreases its speed from
80 km h-1 to 60 km hl in 5 s.
Find the acceleration of the bus.​

Answer 1

given :-

initial velocity = 80 km/hr

final velocity = 60 km / hr

time = 5 sec

to find :-

acceleration

solution :-

a = final velocity - initial velocity / time

a = 60 - 80 / 5

a = -20 / 5

a = -4

hence acceleration is - 4 m/s
