Dear pls type the question I am not able to understand...

Answer 2

Answer:

your answer is here buddy (θ‿θ)

Explanation:

condition 1:-)

here , intial speed = 36 km/ h

= 36×1000m/60×60s

= 10 m/ s

final speed,v = 90km/h

=90×1000/60×60

= 25m/s

Acceleration,a=?

time =3s

we know that-

v=u+at

25 = 10+a×3

25-10=3a

15=3a

15/3=a

5=a

therefore, acceleration = 5m/s²

condition 2:-)

distance covered ,s =?

as we know -

v² = u²+2as

25²=10²+2×5×s

625 = 100+10s

625 -100=10s

525 =10s

525/10 = s

52.5 = s

therefore, distance covered = 52.5 m

hope it's help you
