A ball is thrown with an initial velocity of vi = 6 m/s at a 60 angle from the horizontal as shown in the diagram. Use this to answer the following 3 questions.

 

 

1. Describe where on the portion of the diagram that is applicable to the calculation. (aka where is this calculation applicable) *

⚪ A

⚪ B

⚪ C

⚪ D

⚪ E

⚪ Other: _________

 

 

What is the initial vertical velocity?

I never some help with this physics 12 question 

This is a physics question using static friction:

An ice fishing hut weighing 52 N sits on a dry, frozen lake.

(a) What is the magnitude of the initial horizontal force required to make the ice-fishing hut start sliding across the surface of the frozen pond?

Hi, I'm having trouble with this physics problem, any help you canoffer would be great! Thank you!

Hi! I need some help with this physics question, any that you cancontribute would be great :)

Monochromatic light illuminates a narrow slit which is 4.0m from ascreen. Two very narrow parallel slits 0.5 mm apart are placedhalfway between the single slit and the screen so that interferencefringes are obtained.
a. If the distance between five bright fringes is 10 mm calculatethe wavelength of the light
b. What will be the effect on the fringes of i. halving thedistance between the double slit and the screen, ii. halving theslit separation, iii. covering one of the double slits, iv. usingwhite light.

Thank you again!
