Impulse and Momentum, 2 dimension

AI Thread Summary
The discussion revolves around calculating the impulse experienced by a baseball after being hit by a bat. The initial velocity of the baseball is 32.0 m/s [E], and after contact, it changes to 52.0 m/s [W 20 N]. The user attempts to apply the impulse-momentum theorem using the formula F_net Δt = m(v2 - v1) and breaks down the velocities into their x and y components. Despite calculating the net forces and attempting to find the total impulse using the Pythagorean theorem, the user feels confused and believes they may have made an error in their approach. Clarification and guidance on the correct application of the impulse-momentum principle are requested.

Been stuck on this question for days and any help would be greatly appreciated

A baseball going horizontally at 32.0 m/s [E] with a mass of 0.152 kg is hit by a bat for 0.002 seconds. the velocity after the ball after contact is 52.0 m/s [W 20 N]

Find the impulse experienced by the ball. (I'm guessing total impulse, first vector and the other)

pretty much what i have to work with is F net Δt = m(v2-v1)


Tutors keep telling me I'm wrong without pointing me in the right direction just adding more confusion. here is what i did. ...

V1 being its initial vector

v1x = 32cos0 = 32
v1y = 32sin0 = 0

V2 being after collision

v2x = -52cos20 = -48.864
v2y = 52sin20 = 17.785

now applying Fnet Δt = m(v2-v1) for x and y components.

fnetx Δt = m(-80.864)
fnetx(0.002)=0.152(-80.864)
fnetx = -6145.664

then same stuff for y

fnety =1351.664

after that i use both values to plug into a triangle then Pythagorean to find unknown side which to me seems like it would be the impulse of the ball. which i got 6292.5 kg m/s.

I need help with this, I just can't seem to rack my brain around what is wrong. Things I'm pretty sure I need to use is the fnet Δt=m(v2-v1) and some kind of triangle.

Thanks a lot in advance guys.

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...
