Question

1.
A bus moving
a melocity of 40 km/h, a driven
applies brakes And the bus at stops after lo sec.
what type of acceleration did the bus possess? give reasons for your response
​

Answer 1

Answer:

in the given equation

u=40m/s

v=0m/s

t=10m/s

and a=?

we know the formula V=u+at so putting the values we get 0=40+a×10

-40=10a

-4=a

we get acceleration is-4so retardation will be+4m/sec sq.

hope it's help ✌
