We know, a = v/t
Here, a = 5 m/s²
v = 50 km/h= 13.88 m/s
Substitute their values into the expression:
5 = 13.88 / t
t = 13.88/5
t = 2.78 sec
Now, we know, v = d/t
13.88 = d/2.78
d = 13.88 * 2.78
d = 38.53 meter
In short, Your Answers would be:
i) It will take 2.78 sec
ii) It will travel for 38.53 m after a brakes applied.
Hope this helps!
I think you meant what is "Dark matter" if so the answer is Dark matter is a hypothetical form of matter that is thought to account for approximately 85% of the matter in the universe.
