Graphical Velocity Determination

AI Thread Summary
The discussion revolves around determining the initial velocity of a ball thrown on Planet Exidor, given its velocity at t=1.00 s. Participants emphasize using kinematic equations and the understanding that gravitational acceleration affects only the y-direction. The student expresses difficulty in solving the problem and has not made any progress. Suggestions focus on analyzing the trajectory and applying relevant physics concepts. The conversation highlights the importance of breaking down the problem using known values and equations.

Below is the first in a series of questions that build on one another; however I cannot solve this initial one. Any help is appreciated.

A physics student on Planet Exidor throws a ball, and it follows the parabolic trajectory shown. The ball's position is shown at 1.00 s intervals until t=3.00 s. At t=1.00 s, the ball's velocity is v=(1.95i+2.32j) m/s. Determine the ball's velocity at t=0.00 s. (Enter your answer in component form. Input the x-component first, followed by the y-component.)

what have you done so far? any quess or attempts you have tried?
 
I've been thinking it over for some time. I can't get anywhere with it. I've done nothing.
 
look at your kinematic equations and remember acceleration due to gravity is only in the y direction.

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'

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...
