Answer:
<h2>The answer is 40 Joules</h2>Explanation:
The kinetic energy of a body can be found by using the formula
<h3>where
m is the mass
v is the velocity
From the question
mass = 5 kg
velocity = 4 m/s
Substitute the values into the above formula and solve
We have
<h3>We have the final answer as
<h3>40 Joules</h3>Hope this helps you
Answer:
magnitude of vector is 276.19 kg m/s
Explanation:
The initial momentum is vector of magnitude
And driven in a coherent manner with initial vector.
same magnitude is momentum after the impact, but it is oriented perpendicularly to initial momentum vector.
So, you have 2 momentum vector of specified magnitude perpendicular to one another.
The contrast between such two vectors is a right angle triangle hypotenuse of 195.3 sides
magnitude of vector is
Answer:
The final velocity of the second player is 6.1 m/s.
Explanation:
The final velocity of the second player can be calculated by conservation of linear momentum (p):
(1)
Where:
: is the mass of the first football player = 110 kg
: is the mass of the second football player = 90 kg
: is the initial velocity of the first football player = 5.0 m/s
: is the initial velocity of the second football player = 0 (he is at rest)
: is the final velocity of the first football player = 0 (he stops after the impact)
: is the final velocity of the second football player =?
By solving equation (1) for we have:
Therefore, the final velocity of the second player is 6.1 m/s.
I hope it helps you!
