It could be stress or strain
In the question it is already given that the football player is 80 kg.
Then the mass of the football player = 80 kg
Velocity at which the football player is running = 8 m/s
<span>Kinetic Energy = 0.5 • mass • square of velocity
Now we have to put the known data in this equation to find the actual velocity of the footballer.
</span> <span></span>So
Kinetic Energy of the footballer = 0.5 * 80 * (8 * 8)
= 0.5 * 80 * 64
= 2560
So the Kinetic energy of the footballer is 2560 joules
Answer:
0.2s
force = change in momentum/ time
time = change in momentum/time
Explanation:
first, let's find the change in momentum
pf-pi
5×(-2) - 5× 2
-20kgm/s = 20kgm/s(by changing the direction of whole system)
time = change in momentum/time
20/100
<u> 0.2s</u>
