Newt's 2nd Law--Non-Equilibrium
Homework Statement
A student is skateboarding down a ramp that is 6.0m long and inclined at 18 degrees with respect to the horizontal. The initial speed of the skateboarder at the top of the ramp is 2.6 m/s. Neglect friction and find the speed at the bottom of...
Don't you find the maximum vertical displacement by using the formula y=vytI found the time by using the formula t=1/2gt^2
g= -9.8 m/s^2
to get time= 1.5 seconds
I then found the vertical velocity by using sine(trig)
sin60º(75) to get 64.95 m/s
Then Plugged it in
y= 64.95(1.5)
=97.4m -...
Homework Statement
A rocket is fired at a speed of 75.0 m/s from ground level at an angle of 60.0º above the horizontal. The rocket is fired toward an 11.0m high wall, which is located 27.0m away. By how much does the rocket clear the wall?

I have a homework assignment, teacher didn't have corrections sheets so I'm checking my answers on here. Hope someone can help me out on some problems as well.
1) A diver runs horizontally wit a speed of 1.20 m/s off a platform that is 10.0m above the water.
(a) How long will it take the...
Can someone relate the numbers that go with the variables? That way it'll make the problem easier. I still haven't been able to figure this out, and it's killing me.
My uncle told me...
d= V[SIZE="1"]ot, which algebraically would be distance/velocity
so i got .5/200=.0025 but for some...
Those variables arn't the same in my textbook. Unfortunately, my book was copyrighted in 1992, I use v as the final velocity, Vo as the final d, don't know what you mean.
PHYSICS SUCKS AND IM GOING TO FAIL SO I QUIT
I can't even do VECTORS.
Want to tell me what those variables stand for? Thanks.
(V, I don't have the velocity, f? wtf does that mean? i? wtf? I can't even get the acceleration b/c i don't know the velocity.
Homework Statement
A bullet leaves the muzzle of a gun at a speed of 400 m/s. The length of the gun barrel is 0.50 m. Assuming the bullet was uniformly accelerated, (a) what was it's average speed inside the barrel? (b) how long was the bullet in the gun after it was fired?
Homework...
I got it! Or at least I think I do. One of the answers is 200N East, The other one is 200 N West. How Did i get this?
The sum equals 400, so 200+200= 400N east, since it's already pointing east in the first place.
When it goes west, it's different.
It starts pointing due east at 200N...
y would equal 13.23, but i don't know what that has to do with anything~
lol
i got classes tomarrow, I'll just ask my teacher to help me. thanks anyways guys.
