1. Physics Angle Problem

Vyi= sqrt of vyf^2 + 2g divided by y?
2. Physics Angle Problem

would i have to isolate the formula?
3. Physics Angle Problem

so would the equation be Vyf^2 = Vyi^2 + 2g(delta y)
4. Physics Angle Problem

velocity along the y axis
5. Physics Angle Problem

the velocity ?
6. Physics Angle Problem

how far (delta y) the water balloon would go?
7. Physics Angle Problem

the water balloon should just graze the ceiling which is 3.3 meters tall and is going at a initial velocity at 9.7 m/s

I dont know
9. Physics Angle Problem

i need to find the angle. i really do not know which equation to use...
10. Physics Angle Problem

Homework Statement Some enterprising physics students working on a catapult decide to have a water balloon ﬁght in the school hallway. The ceiling is of height 3.3 m, and the balloons are launched at a velocity of 9.7 m/s. The acceleration of gravity is 9.8 m/s2 .At what angle must they...
11. Help With finding displacement in uniform acceleration

delta x = 1/2 (1.51)(5.6394)^2 delta x = 24.0111384 that is what i got this time.....
12. Help With finding displacement in uniform acceleration

i also did substitute 5.6394 s for the time rather than 7.8 seconds, and i got 66.4208532002 for delta x. but this was wrong. what did i do wrong?
13. Help With finding displacement in uniform acceleration

Homework Statement A subway train starting from rest leaves a station with a constant acceleration. At the end of 7.8 s, it is moving at 11.778 m/s. What is the train’s displacement in the ﬁrst 5.6394 s of motion? Answer in units of m Homework Equations a= velocity final - velocity...
14. Help With finding initial vertical speed

ok, i have one more question i need help with....
15. Help With finding initial vertical speed

so the initial vertical speed would be 11.8793939239 m/s ?
