Answer:
2 and a half hours
Explanation:
Nancy rides her bike at 10 miles per hour. After the first hour, she would have ridden 10 miles. After the second hour, she would hvae ridden 20 miles. She needs to ride 5 more miles, which is half of her 10 miles that she rides every hour. Since it is half of her speed of miles per hour, it will take her another half an hour to ride the 5 miles. Added together, Nancy takes 2 and a half hours.

Examples of non-inertial reference frames
One clearcut example of an inertial reference frame is an isolated spaceship, far, far away from the Earth, the Sun, the Milky Way Galaxy, and all other massive objects. Fred places a blue ball into a claw at the left end of the ship, and red ball into a claw at the right end of the ship.
Explanation:
Let us say that you are in a car at a stop light. The car is standing still. The light turns green, and the car accelerates forward. While undergoing this acceleration, the car is a non-inertial frame of reference.
Answer:
The change of the momentum of the ball is 
Explanation:
We should find 
(1)with 
the initial momentum and 
the final momentum. Linear momentum is defined as 
, using that on (1):
(2)
It's important to note that momentum and velocity are vectors and direction matters, so if +x direction is the direction towards the wall and the -x direction away the wall 
and 
so (2) becomes:
B, heat, is the correct answer. Heat is represented by a capital q in thermodynamic equations.
