1.	A car is moving at a velocity of 54 km/h ^-1 . Suddenly brakes are produced a declaration of 6m/^2 , find the distance covered by the car before coming to rest ?Pls answer fast
Answer» ANSWER: U = 54 km/h= 54× 1000/3600= 15 m/s v= u + at 0= 15 + 6.t 6.t = -15 t = -15/6= -5/2 So distance covered in 5/2 seconds S = ut + 1/2 at² = 15× 5/2 + 1/2 × 6 × 25/4 = 75/2 + 75/4 = (75× 3)/ 4 =225/ 4 = 56.25 m

Answer»

ANSWER:

U = 54 km/h= 54× 1000/3600= 15 m/s

v= u + at

0= 15 + 6.t

6.t = -15

t = -15/6= -5/2

So distance covered in 5/2 seconds

S = ut + 1/2 at²

= 15× 5/2 + 1/2 × 6 × 25/4

= 75/2 + 75/4

= (75× 3)/ 4

=225/ 4

= 56.25 m
