I think it’s the last one
Hope this helps
- Displacement = 10 m
- Time = 5 s
- We know,
- Therefore, the car's velocity
<h3>Answer:</h3>
The car's velocity is 2 m/s.
Hope you could get an idea from here.
Doubt clarification - use comment section.
Answer:
For example: Freezing, boiling, are physical
Explanation:
The average speed will be:
Total distance travelled divided by time taken
Total distance (in metres)= 80+125+45=250
Total time (minutes) =10
250/10
=25
Thus Mary's average speed is 25 metres per minute.
im not sure about most of this but ill try to help
so there are three formulas you need to know first: the formula for rate distance and time.
to find distance:
distance = rate * time
to find time:
time = distance / rate
and to find rate (which is what we need)
rate = distance / time
now we just use our formula and plug in the numbers
rate = distance * time
rate = 160 / 2 = 80
so our rate is 80. thats all i know i have no idea about the rest but i always use these messurments. im sure you can google most of it to get other formulas and calculators though. sorry i couldnt help much! good luck :D
