OK, well the spring moved 0.0214 m and the F involved is 91.995 N.
W = F d
W = (91.995 N) (0.0214 m)= 1.968693 J
The homework program on the computer is telling me this is wrong. I don't know why. Do you think this is OK? Sometimes the program is mistaken.
Homework Statement
I already found A, but I keep getting wrong answers for B.
A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Friction is absent. The spring constant of the spring is 4300 N/m. The piston has a...
I can't read any of your equations. Anyway, I realized that I calculated v incorrectly. How did I get that number? I have no idea. v = 15.33 and now that I plug that into my work, my solution is correct. Still have no idea what you're talking about but this way works. Behold my works ye mighty!
I've never seen that equation before and I don't understand what it is. Why doesn't my solution work? I found KE? Is that equation the only way to find the solution?
OK, she hits water level at 117.6 m/s.
KE = 0.5 x 53 x (117.6^2) = 366488.64
delta KE = Fd
366488.64 = Fx3
366488.64/3=F
122162.9 =F
?
That is not an option but it seem right to me. :(
The kinetic energy when the diver hits the water is equal to the kinetic energy the water exerts, right? Because of cons of E? So if I can find the diver's E when she has gone 12 m, I will know the avg F?
A 53.0-kg person jumps from rest off a 12.0-m-high tower straight down into the water. Neglect air resistance. She comes to rest 3.00 m under the surface of the water. Determine the magnitude of the average force that the water exerts on the diver. This force is nonconservative.
A. 2100 N B...
A ball is released on the inside surface of a half-pipe. The left side of the pipe is rough, so that the ball rolls there without slipping. The right side of the pipe is coated with frictionless ice. If the ball is released from a height h on the left side, how high will it go on the right side...
Gravity? And the spring?
They equal zero? I think I'm missing something. Like how to figure in this angular business.
x = (mg/k)
x=(9.8x8.5)/184
x=0.565 m<~~~ not right
A 8.5 kg board is wedged into a corner and held by a spring at a 50.0° angle, as the drawing shows. The spring has a spring constant of 184 N/m and is parallel to the floor. Find the amount by which the spring is stretched from its unstrained length.
(The picture shows a spring sticking out...
Objects of equal mass are oscillating up and down in simple harmonic motion on two different vertical springs. The spring constant of spring 1 is 186 N/m. The motion of the object on spring 1 has 3 times the amplitude as the motion of the object on spring 2. The magnitude of the maximum velocity...
