Matthew is cycling of a speed of 4 meters per second . when he starts down the hill the bike wheb he starts down a hill , the bike accelerates at a rate of 0.4 m/s squared the vertical distance from the top of the hill to the bottom of the hill is 25 m is the equation d(t)=v0t+1/2 at^2 two find how long it will take mathew to ridedown the hill

Mathew will take 5 seconds to ride down the hill.

Step-by-step explanation:

Given equation is:    

Matthew is cycling of a speed of 4 meters/second. So,  

When he starts down a hill, the bike accelerates at a rate of 0.4 m/s². So,  

The vertical distance from the top of the hill to the bottom of the hill is 25 meters. So, meters.

Plugging the values into the above equation, we will get......

Using quadratic formula, we will get.......

(Negative value is ignored as the time can't be negative)

So, Mathew will take 5 seconds to ride down the hill.

your answer would be b
