Abike that is coasting down a steep hill increases its speed from 8.0 m/s to 14 m/s. the length of the hill is 55 meters. how much time passes during the descent?

Time, t = 5 seconds          

Explanation:

It is given that,

Initial speed of the bike, u = 8 m/s

Final speed of the bike, v = 14 m/s

Length of the hill, d = 55 m

Firstly, we can find the acceleration of the bike. Let it is equal to a. It can be calculated using third equation of motion as :

Let t is the time passes during the descent. It can be calculated using the first equation of motion as :

t = 5 seconds

So, the time passes during the descent is 5 seconds. Hence, this is the required solution.                                                      

answer is slate

hope this
