1. calculate agni's average speed during the race.
2. the average speed of agni within the first 20 km ( number 1 in the graph ) can be calculated using the slope of the graph :
distance : time = 20 km : 1/2 hour = 40 km/hour

B. 1. what quantities can be identified in the graph?
    2. explain the meaning of the horizontal lines in the graph.
     3. calculate agni's velocity during the race.
     4. calculate the speed reached by agni at the end of the race.


on independence day, there was a bicycle race organized in a neighborhood. an observer took notes on the progress of one participant, named agni. who finally won the race...  the collected data is shown in " graph of agni's bicycle track " as shown below

1 Calculate Agnis Average Speed During The Race2 The Average Speed Of Agni Within The First 20 Km Number 1 In The Graph Can Be Calculated Using The Slope Of The class=

Sagot :

The formula to find the speed/velocity is : 
v = Δx/Δt = ([tex] \frac{ x_{final} - x_{initial} }{ t_{travel} } [/tex]

B.
1. From the graph given, we can get an information such as the distance travelled, and the time given.
2. If the graph are horizontal, it means that the Agni's speed is zero because Agni doesn't move.
3. If the question ask the velocity during all time, we can say that the velocity is :
.[tex]v = \frac{x}{t} = \frac{50 km}{2.5 hour} = 20 \frac{km}{h} [/tex]
4. So, the final velocity can be found by looking the third part of the graph. So,..
[tex]v = \frac{x}{t} = \frac{(50-35) km }{0.5 hour} = 30 \frac{km}{h} [/tex]
