Explanation:
It is given that,
Mass of the football player, m = 92 kg
Velocity of player, v = 5 m/s
Time taken, t = 10 s
(1) We need to find the original kinetic energy of the player. It is given by :
k = 1150 J
In two significant figure, 
(2) We know that work done is equal to the change in kinetic energy. Work done per unit time is called power of the player. We need to find the average power required to stop him. So, his final velocity v = 0
i.e. 
P = 115 watts
In two significant figures, 
Hence, this is the required solution.
Salt and pepper, soda, chocolate chip cookies, or a Twix™ candy bar, ... are all examples of heterogeneous mixtures<span>, where substances are not mixed on a molecular level.
</span><span>Water itself is an example of a homogeneous mixture. It often contains dissolved minerals and gases, but these are dissolved throughout the water. Tap water and rain water are both homogeneous, even though they may have different levels of dissolved minerals and gases.</span>
No, they actually travel through the vacuum of outer space, but it also requires the absence of a material sedium.
