A 110 kg football player running with a velocity of 5.0 m/s hits another stationary football

KengaRu [80]

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):

$p_{i} = p_{f}$

$m_{a}v_{a_{i}} + m_{b}v_{b_{i}} = m_{a}v_{a_{f}} + m_{b}v_{b_{f}}$ (1)

Where:

$m_{a}$ : is the mass of the first football player = 110 kg

$m_{b}$ : is the mass of the second football player = 90 kg

$v_{a_{i}}$ : is the initial velocity of the first football player = 5.0 m/s

$v_{b_{i}}$ : is the initial velocity of the second football player = 0 (he is at rest)

$v_{a_{f}}$ : is the final velocity of the first football player = 0 (he stops after the impact)

$v_{b_{f}}$ : is the final velocity of the second football player =?

By solving equation (1) for $v_{b_{f}}$ we have:

$110 kg*5.0 m/s + 0 = 0 + 90 kg*v_{b_{f}}$

$v_{b_{f}} = \frac{110 kg*5.0 m/s}{90 kg} = 6.1 m/s$

Therefore, the final velocity of the second player is 6.1 m/s.

I hope it helps you!

A clock is designed that uses a mass on the end of a spring as a timing mechanism. If the oscillation time needed is exactly one

user100 [1]

Answer:

The value is $k = 51.34 \ N/ m$

Explanation:

From the question we are told that

The mass is $m = 1.3 \ kg$

The needed oscillation time is $T = 1 \ s$

Generally the spring constant is mathematically represented as

$k = \frac{4 \pi^2 * m }{ T^2}$

=> $k = \frac{4* 3.142^2 * 1.3 }{ 1^2}$

=> $k = 51.34 \ N/ m$

Which determines the pitch of a sound? A. At the same wavelength, the sound with the most cycles per second will have the highes

kipiarov [429]

This would be known to be determined by its sound wave which would be the amplitude. The pitch of sound would actually be a little differenr in this matter. But know that we know and understand the sound wave of the pitch of sound, we know that this is done by amplitude.
