1) What happens to the average speed as distance increases? 2) How do forces cause objects to slow down or speed up?

Explanation:

1. Average Speed formula is

As the distance increases, and the time remains constant, thr speed increases as well

2. Forces cause object to speed up or slow down by extering a greater force on a object than its force that opposes it. For example, if a person is running. The pushing force ( the person using their legs to run) is greater than the friction force. which is from the ground.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
