Question

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

Answer 1

Explanation:

if an object speed increase at a constant rate then we say that it is in uniform acceleration

initial velocity,u =60, fin al velocity,v

= 80

acceleration= v_u|5

80_60|5

20|5

Answer 2

Answer:

-10/9 m/s2

Explanation:

Initial velocity of bus = 80km/h = 80×5/18 m/s = 200/9 m/s

Final velocity of bus = 60km/h = 60×5/18 m/s = 150/9 m/s

time taken = 5 s

According to first equation of motion,

v=u+at

a=(v-u)/t

=(-50/9)/5

$\frac{ - 10}{9} \frac{m}{ {s}^{2} }$
