AI Thread Summary
To calculate Fmax for the tennis ball collision, first determine the acceleration using the change in velocity and the time of contact. The initial speed is 30.5 m/s, and since the ball rebounds with the same speed, the change in velocity is 61.0 m/s (30.5 m/s to -30.5 m/s). Using the formula Fnet = ma, where m is the mass of the ball (0.053 kg) and a is the calculated acceleration, Fmax can be derived. The force diagram mentioned is crucial for visualizing the forces involved, and sharing it in a more accessible format may help others provide better assistance. Understanding these steps will clarify the approach to solving for Fmax.

I am having trouble with this question, I know what I need to find, just don't know what route to take.

A 53.0 g tennis ball with an initial speed of 30.5 m/s hits a wall and rebounds with the same speed. The figure below shows the force of the wall on the ball during the collision. What is the value of Fmax, the maximum value of the contact force during the collision, if the force is applied for ti=26.4 ms?

I was wondering should I use Fnet=ma to find Fmax, but find acceleartion first

Any help would be great
Thanks

The figure doesn't work. You may want to post a link or something.
 
I have attached the diagram, its a word document

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
