Look at the graph above. it shows how three runners ran a 100 meter race

1.) which runner won the race?

2.) which runner stopped for a rest?

3.) how long was the stop?

4.) how long did bob take to complete the race?

5.) calculate albert’s speed. (figure the distance and the time first! )

i need the questions immediately! answer all five! i will give loads of points and make the brainliest!

1. Albert

2. Charlie

3. 5 seconds

4. 14 seconds

5. 8.33... meters per second

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
