How does the momentum of a 75 kilogram stationary football player compare with a 70 kilogram player moving at a velocity of 6 meter/second
To compare the momentum of the two players, we need to calculate the momentum of each player. The momentum of an object is given by the formula:
Momentum = mass * velocity
For the 75 kilogram stationary football player, since he is stationary, his velocity is zero:
Momentum = 75 kg * 0 m/s = 0 kg*m/s
Therefore, the momentum of the 75 kilogram stationary player is zero.
For the 70 kilogram player moving at a velocity of 6 m/s:
Momentum = 70 kg * 6 m/s = 420 kg*m/s
Therefore, the momentum of the 70 kilogram player moving at a velocity of 6 m/s is 420 kg*m/s.
In conclusion, the momentum of the 70 kilogram player moving at a velocity of 6 m/s is greater than the momentum of the 75 kilogram stationary player.
To compare the momentum of the two players, we can use the formula for momentum:
Momentum = mass x velocity
For the stationary player, the mass is 75 kg and the velocity is 0 m/s since they are not moving. Therefore, the momentum of the stationary player is:
Momentum = 75 kg x 0 m/s = 0 kg m/s
For the moving player, the mass is 70 kg and the velocity is 6 m/s. Therefore, the momentum of the moving player is:
Momentum = 70 kg x 6 m/s = 420 kg m/s
Comparing the two, we can see that the momentum of the moving player is 420 kg m/s, while the momentum of the stationary player is 0 kg m/s. Thus, the momentum of the moving player is greater than that of the stationary player.
To compare the momenta of the two players, we need to first calculate the momentum for each player.
Momentum is defined as the product of an object's mass and its velocity. Mathematically, momentum (p) can be calculated using the formula:
p = m * v,
where
p = momentum,
m = mass of the object,
v = velocity of the object.
Let's calculate the momentum for each player:
For the 75 kilogram stationary football player:
m1 = 75 kg (mass of the player)
v1 = 0 m/s (velocity of the player since he is stationary)
p1 = m1 * v1
= 75 kg * 0 m/s
= 0 kg·m/s
For the 70 kilogram player moving at a velocity of 6 m/s:
m2 = 70 kg (mass of the player)
v2 = 6 m/s (velocity of the player)
p2 = m2 * v2
= 70 kg * 6 m/s
= 420 kg·m/s
Comparing the momentum of the two players, we find that the stationary player has a momentum of 0 kg·m/s, while the moving player has a momentum of 420 kg·m/s. Therefore, the momentum of the 70 kilogram player moving at a velocity of 6 m/s is greater than the momentum of the 75 kilogram stationary player.
