Answer:
The average velocity is
and respectively.
Explanation:
Let's start writing the vertical position equation :
Where distance is measured in meters and time in seconds.
The average velocity is equal to the position variation divided by the time variation.
= Δx / Δt =
For the first time interval :
t1 = 5 s → t2 = 8 s
The time variation is :
For the position variation we use the vertical position equation :
Δx = x2 - x1 = 1049 m - 251 m = 798 m
The average velocity for this interval is
For the second time interval :
t1 = 4 s → t2 = 9 s
Δx = x2 - x1 = 1495 m - 125 m = 1370 m
And the time variation is t2 - t1 = 9 s - 4 s = 5 s
The average velocity for this interval is :
Finally for the third time interval :
t1 = 1 s → t2 = 7 s
The time variation is t2 - t1 = 7 s - 1 s = 6 s
Then
The position variation is x2 - x1 = 701 m - (-1 m) = 702 m
The average velocity is
True because cooler particles have less kinetic energy in them
Thinking back to my classes from last year, I'm pretty sure it's gas as the cells move faster and are spread apart more than in a solid form.
Answer:
Explanation:
given,
speed limit on the highway is roughly = 100 km/hr
a) to calculate limit in meter per second
1 km/h =
100 km/h =
= 27.78 m/s
b) to calculate limit in meter per second
1 km = 0.6213 mile
100 km/hr = 100 × 0.6213 mi/hr
= 62.13 mi/hr
