AI Thread Summary
In a perfectly inelastic collision between a fullback weighing 89.3 kg running east at 4.91 m/s and a 94.7 kg opponent running north at 2.98 m/s, the combined speed and direction post-collision can be calculated using momentum conservation principles. The resulting speed is approximately ___ m/s at an angle of ___° north of east. Energy loss during the collision can be determined by comparing the initial kinetic energy of both players to the final kinetic energy after the tackle. The energy lost is calculated as ___ J, which accounts for factors such as sound, heat, and deformation during the impact. This analysis highlights the physics of collisions in sports contexts.

A 89.3 kg fullback running east with a speed of 4.91 m/s is tackled by a 94.7 kg opponent running north with a speed of 2.98 m/s.

(a) If the collision is perfectly inelastic, calculate the speed and direction of the players just after the tackle.
___m/s___° (north of east)
(b) Determine the energy lost as a result of the collision.

___J
Account for the missing energy.

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...

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
