Your average speed was
(100 m) / (13.8 s) = 7.25 m/s .
If you finished 0.001s ahead of him, then at your average speed, that corresponds to
(7.25 m/s) x (0.001 s) = 0.00725 m
That's 7.25 millimeters ... about 0.28 of an inch !
NOTE:. I think this is only valid if your speed was a constant ~7.25 m/s all the way.
Answer:
Explanation:
<u>Average Density
</u>
The density of an object of mass m and volume V is
If we know the density and the volume occupied by the object, the mass can be computed as
The tank can hold 20 L of gasoline when full. Converting to cubic meters
That's the volume of the gasoline it contains. Knowing the density of the gasoline, we get the mass of gasoline.
To know the total mass of both, we add the 2.5 kg of the tank
The volume of the tank is computed solving for V
The total volume is
The average density is
Gravity is an attractive force that works to pull objects together. If 2 objects are close the gravitational pull will be stronger
Mass and distance determine gravity. The farther two things are away from each other, the weaker the gravitational forces are, the less mass an object has the less gravitational force it exerts
Answer:
Both balls have the same speed.
Explanation:
Janelle throws the two balls from the same height, with the same speed. Both balls will have the same potential and kinetic energy. Energy must be conserved. When the balls pass Michael, again they must have the same potential and kinetic energy.
