Atennis ball of mass 57 g travels with velocity < 70, 0, 0 > m/s toward a wall. after bouncing off the wall, the tennis ball is observed to be traveling with velocity < -65, 0, 0 > m/s. -what is the magnitude of the change of momentum of the tennis ball? -what is the change in the magnitude of the tennis ball's momentum? explain

1) The magnitude of change in momentum is 7.695 kgm/s.

Explanation:

We know that momentum of a particle with mass 'm' travelling with a speed of 'u' is mathematically given by

Thus according to the given values initial momentum of the ball is

The final momentum of the ball after bouncing off becomes

Thus the change in momentum is given by:

Thus the magnitude of change in momentum is 7.695 kgm/s.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
