First convert 90km/hr to m/s.
Initiate velocity = 0m/s (car was at rest)
Final velocity is 25m/s (90km/hr converted)
25m/s - 0m/s / 8s = 3.125 m/s^s
Therefore the answer is option A (3.13m/s^2)
Answer:
Explanation:
we know that
s=vt here v is the speed and s is distance covered by the signals
given data
v=3*10^8
t=10 min we have to convert it into seconds
1 minute=60 seconds
so
10 minutes =10*60/1 =600 seconds
now putting the value of v and t we can find the value of s
s=vt
s=3*10^8*600
s=1.8*10^11m
i hope this will help you
<u>Combustion Reaction</u> :- it is a type of reaction where a compound and an oxidant is reacted to produce heat and new product .
Michael uses a car that burns fossil fuels : - Combustion reaction
<u>photosynthesis</u> :- the process use by green plants in which plants uses sunlight to convert carbon dioxide in to sugars that the cells can use as energy
Alan grow tomato in his farm :- photosynthesis
<u>Respiration</u> :- Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water

From my research, the following image is used for the problem. For each segment, the displacement can be obtained by looking for the area under the segment.
Part A:
displacement = (1/2)*10*2 = 10m
Part B:
displacement = [(1/2)*4*5] + (5*2) = 20m
<span>Part C:
</span>
displacement = [(1/2)*4*10] + (2*10) = 40m
