Impluse and average force question. Need Help

AI Thread Summary
The discussion revolves around calculating the impulse and average force exerted on a golf ball after being struck by a club. The golf ball has a mass of 0.045 kg and is hit at a speed of 42 m/s, with contact time of 4.7 x 10^-3 seconds. To find the impulse, the formula used is Impulse = change in momentum, which can be calculated from the mass and velocity. The average force can be determined using the relationship Impulse = F * dt. The calculations are essential for understanding the dynamics of the golf swing and the forces involved.

A golf ball of mass 0.045 kg is hit off the tee at a speed of 42 m/s. The golf club was in contact with the ball for 4.7 10-3 s.
(a) Find the magnitude of the impulse imparted to the golf ball.
N · s
(b) Find the magnitude of the average force exerted on the ball by the golf club.
N

Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
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...
